We are now prepared to include the source that shows our first full page - a homepage for the LocalLibrary website...! Our home page shows the number of data sets we have for each particular style and provides navigational references in the side bar to our other pages...! Our goal is to help our clients to improve their URLs by providing them with the most up-to-date URL mapping and viewing tools available, as well as by providing them with the ability to retrieve data from the data base and use templates.

Once we have delineated our model and produced some preliminary recordings of the libraries we can work with, it is appropriate to start writing the coding that presents this information to people. First thing we need to do is decide what information we want to show on our pages, and specify the URIs that will be used to return those ressources.

Then, we build a mapping tool, maps and templates to show the pages. Use the following chart to describe the most important dataflow and component needed to handle HTTP request and response. Since we have already built the models, the key elements we are going to build are: to forward the sponsored urls (and all information coded in the urls) to the appropriate viewer function.

Viewing features to obtain the required information from the model, generate HTML pages that show the information, and send the pages back to the end users to show in the web browsers. The templates to be used when you render files in the layers. You will see in the next section that we have 5 pages to show what is too much information to cover in a simple report.

Therefore, this paper will concentrate on the implementation of the homepage, and we will discuss the other pages in a following paper. It should give you a good end-to-end comprehension of how mapping URLs, view and model work in use. Given that this release of LocalLibrary is basically read-only for end use, we only need to create one target page for the website (a home page) and pages displaying lists and detail view for book and author.

As an example, the third volume added to the listing is /catalog/book/3. catalog/author/ - The detail page for each individual writer with a prefix. With the first three addresses the index page, the library listing and the publisher listing are returned. Those urls do not code any extra information, and the requests that retrieve information from the databank are always the same.

The last two addresses, on the other hand, show details about a particular title or authors. This URL encodes the identities of the elements to be displayed (represented by above). URL mapping extracts the coded information and passes it to the viewer, and the viewer determines what information is available from the data base in a dynamic manner.

Coding the information in the web address, we use a unique phrase of a web address map, a browser window, and a templates to manage all the book (or author). Django docs recommend coding information in the text bodies of URLs for better design of URLs. The remainder of this paper explains how to build the index page.

First page we will make is the index page (catalogue/). This index page will contain some HTML stats, along with generate "counts" of various datasets in the data base. For this to work, we build a map of URLs, a map of views, and a sample for it. The most information also apply to the other pages that we will be creating.

At the time we built the websitekeleton, we upgraded the locallibrary/urls. py to make sure that each time a catalogue/ starting URLConf catalogue receives a link, the modules catalogue handles the rest of the strings.

In addition, we have added a wildcard filename /catalog/urls.py for the URLLConf-Modul. Append the following rows to this file: path('''', views. index, name='index'), the command path() will define the following: We' ll be discussing in detail our samples of URLs when we work on the other viewpoints. This is a viewer feature that is invoked when the given layout is recognized: opinions. index, which is the index() feature in the opinions. py files.

Also, the path() command provides a name argument, which is a distinct identification for this particular type of map. The name can be used to "reverse" the name of the mapper, i.e. to generate a dynamic url that refers to the resources for which the MAAPER is intended. As an example, we can use the Name argument to point to our home page from any other page by inserting the following reference into a template:

Hint: We can hardcode the links like in Home), but if we modify the patterns for our homepage, e.g. in /catalog/index), the templates will not be linked any more. This is a feature that handles an HTTP query, retrieves the necessary information from the underlying databases, uses an HTML templates to render the information in an HTML page, and then uses an HTTP reply to return the HTML created to show the page to the end users.

Indexing follows this approach - it retrieves information about the number of Book, BookInstance, available BookInstance, and Author entries we have in the repository and submits that information to a presentation for viewing. Now open the catalog/views. py and notice that the resulting image already imported the Render() link to create an HTML document with a sample and data:

Make your opinions here. Add the following line to the end of the file: def index(request): "The " ""View feature for the home page of the website." num_books': num_books, < _instances_available': num_instances_available, _authors': num_authors, In the first line the style categories are imported with which we will be able to import information into all our displays.

First part of the look functions gets the number of datasets via the object. all() attributes on the style class. For more information about accessing your modeling information, see our earlier online tool titled Part 3: Using Dynamics > Finding Datasets, in our earlier tool titled Using Dynamics. We call the render() at the end of the viewer functionality to generate an HTML page and send the page back as a reply.

These shortcuts include a number of additional features to facilitate a very frequent application. By default, the Render() utility will accept the following parameters: the initial requirement item, which is an HttpRequest, an HTML templates with wildcards for the dates, a Python ABAP Query environment that is a Python ABAP/4 Dictionary and contains the dates to be inserted into the wildcards.

In the next section we will discuss more about templates and the shortcut variables. Let's start by making our templates so we can actually show something to the users! This is a text document that specifies the text format or format of a document (such as an HTML page) and uses wildcards to indicate its text.

By default it searches for templates in a folder called'templates' in your applications. In the index pane we just added, for example, the render() feature expects to find the index of the files. html in /locallibrary/catalog/templates/ and will cause an issue if the files do not exist. This can be verified by storing the changes you made previously and access 127.0.0. 1:8000 in your web browsers - a fairly straightforward errors screen is displayed:

"templatesoesnotexist at /catalog/", and other detail. Hint: On the basis of the preferences of your projects files your program searches for templates in several places and searches in your installers. For more information about how to find templates and what templates are supported, see the Templates section of the document.

An index style sheet requires default HTML header and body markups and navigation segments to point to the other pages of the site that we have not yet built and to segments that show introducing text and books as well. Most of the HTML and navigational structures will be the same on every page of our website.

Rather than duplicate hotplate coding on each page, you can use the diango templates engine to define a basic style and then expand it to just substitute the bit that is different for each page. Below is a section of an example html based basic source document from a html based_generic database document.

This example contains popular HTML with section for titles, a side bar, and key messages tagged with names of designated book and end book templates and printed in plainface. Empty the pads or add standard text to be used when you render pages that have been inherited from the original. Notice: Style sheet tag are features that you can use in a style sheet to traverse listings, execute conditioned operation on the value of a tag, and so on.

Additionally to the templates you can refer to templates in the templates systax and apply templates filter to your templates (e.g. to change a character to lowercase). "When we define a style sheet for a particular look, we first specify the basic style sheet with the Extended Platetag - see the example below.

We then explain which parts of the style sheet we want to substitute (if any) by using block/end blocks as in the basic style sheet. The following excerpt of source-code, for example, shows how to use the extended template tags and overwrite the contents area. Created HTML contains the HTML definition in the basic HTML document and the HTML tree, but the new HTML table instead of the standard HTML table, along with the standard contents you define in the header area.

The following excerpt of our source is used as a basis for the LocalLibrary website. You can see that it contains some HTML coding and defined block for titles, sidebars and contents. Hint: We have also introduced two extra templated tags: url and load static. of course, you can also use the following templates. The following paragraphs explain these tag types.

Make a new base_generic. html base filename in /locallibrary/catalog/templates/ and add the following source to the filename: "It contains bootstrap style sheets (CSS) to enhance the HTML page appearance and design. The use of Bootstrap (or another client-side web framework) is a fast way to build an appealing page that will look good on different display screens.

Basic templates also reference a locale style sheet (styles. css) that provides extra style. Generate a style. Add the following HTML index to /locallibrary/catalog/static/css/ and add the following HTML index to the file::::::: ; ; Date:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: and and insert the template/templates//////catalog///templates/ and insert the following HTML index into the HTML index.

It adds the first line to our basic style sheet and then substitutes the standard style sheet contents area. section, we define wildcards (template variables) for the information from the point of views we want to capture. Amend the variable with a handlebar (double bracket) as shown in the example above.

Hint: You can recognize templates variable and templatedags ( Funktionen ) easy - variable are placed in duplicate brackets ({{ num_books }}), and tag are placed in individual brackets with percent sign ({% extended "base_generic. html" %}). It is important that you name the variable with the keys that we transfer to the ABAP Query conditional ABAP key set in the render() command of our viewer (see example below).

When you render the templates, the system replaces them with the corresponding variable names. You can specify the storage place in your templates in relation to the overall settings set for SIZE_URL in your templates because the storage place of these data may not be known (or may change). Inside the templating first call the load templating tags with "static" to append the templating libraries as shown in the following example.

Then you can use the statically tagged templates and specify the specific filename to use. For example, you can similarly insert an picture to the page: By changing the globale mapping tool (/locallibrary/locallibrary/urls.py) when we built the website framework, we set up the developer web servers to handle data but still need to activate data handling in our work.

Above basic style sheet introduces the day of the HTML style sheet. By accepting the name of a path() command invoked in your urls. py, and the value for all argument (s) the associated viewer receives from that command, this day will return a return URL that you can use to point to the resources.

If you want to browse for your templates in the Templates folders, you must show them. In order to do this, simply append the template directory to the TEMPLATES objects by modifying the preferences. py files as printed in the following example code: < < < < < < 'BACKEND':

Here we have put together all the necessary ressources to show the index page. Please note: The link All book and All author does not work yet, because the path, view and templates for these pages are not yet known. Just added wildcards for these hyperlinks in the base_generic. html templat.

Below are some exercises to test your confidence with models, viewpoints, and templates. LocalLibrary's basic style sheet contains a header area. In the index style, overwrite this field and make a new page heading. Note: The Advanced Templates section describes how to build pads and how to expand pads in another pad.

Change the display to create a count for a genre or book that contains a specific term (case-insensitive), and then contextualize the results. Then, refresh the index style to accommodate these tags. We' ve just finished creating the home page for our website - an HTML page that shows a number of data sets from the data base and hyperlinks to other pages yet to be made.

We learnt basic information about mapping URLs, viewing them, retrieving the model data base, transferring information from a viewing point to a model, building and expanding templates. The next paper will take this information and use it to construct the four pages of our website.
