steps for template in django for project
- 2. TEMPLATE A template in Django is basically written in HTML in a .html file. Django framework efficiently handles and generates dynamic HTML web pages that are visible to the end-user. Django mainly functions with a backend so, in order to provide a frontend and provide a layout to our website, we use templates.
- 3. TEMPLATE In current project, we will create a single template directory/folder that will contain all html files and that can be spread over the entire project for simplicity. Create a folder/directory in command prompt on your project path using DOS (Disk Operating System) command md (make directory) Example : (djangowork) C:UsersLenovoweekdays_django_batchtemplate_inheritance>md template Project path
- 4. TEMPLATE Add template in settings.py file,Write following commands,line no.14 and 17 Variable_ name folder_name Add varaiable name here
- 5. DJANGO TEMPLATE LANGUAGE A Django template is a text document or a Python string marked-up using the Django template language. Some constructs are recognized and interpreted by the template engine. A template contains variables, which get replaced with values when the template is evaluated, and tags, which control the logic of the template. A template is rendered with a context. Rendering replaces variables with their values, which are looked up in the context, and executes tags. Everything else is output as is.
- 6. DJANGO TEMPLATE LANGUAGE The syntax of the Django template language involves four constructs. 1. Variable A variable outputs a value from the context, which is a dict-like object mapping keys to values. Variables are surrounded by {{ }} like this . Use a dot (.) to access attributes of a variable. In html file, we write : <h1>My name is {{firstname}} {{lastname}}</h1> In views .py file create context variable as a dictionary. With context {‘firstname’:’Deepali’ ‘lastname’:’Shinkar’} this template renders to : <h1>My name is Deepali Shinkar</h1> Use a dot (.) to access attributes of a variable.
- 7. DJANGO TEMPLATE LANGUAGE 2. Filter When we need to modify variable before displaying ,we can use filter pipe ‘|’ is used to apply filter. Syntax : {{variable | filter}} Example :{{firstname | upper}} Some of filters take argument : Syntax : {{variable | filter : argument}}
- 8. DJANGO TEMPLATE LANGUAGE Float Format :When used without argument rounds a floating point number to one decimal place but only if there is a decimal part to be displayed. Example : 56.24321 ---{{value | floatformat}} -56.2 56.00 ---{{value | floatformat}} -56 56.3700 ---{{value | floatformat}} -56.4 56.24321 ---{{value | floatformat:2}} -56.24
- 9. DJANGO TEMPLATE LANGUAGE 3.Tags Tags provide arbitrary logic in the rendering process. Tags are surrounded by {%%} like this. Examples : Some tags require beginning and ending tags. {% csrf_token %} {% url ‘add’ %} {% includes ‘base.html’ %} etc.
- 10. DJANGO TEMPLATE LANGUAGE Some tags require beginning and ending tags. Like this If tag : It executes a variable and if that variable is true then execute html tag inside a if body. Syntax : For tag : Evaluate a for loop any number of times which is depend on iterable object. Syntax : {% if variable or condition %} Html tags {% endif %} {% for variable in iterable_object %} {{variable}} {% endfor %}
