Qty: current page in query variable

Question

In the template, how do I get which page I'm on now? I would prefer not to pass a variable like page , especially when I know that request.xxx can provide me with information.

 <li {% if page=="home" %}class="active"{% endif %}> <a href="/">Home</a> </li> <li {% if page=="about" %}class="active"{% endif %}> <a href="/about">About</a> </li> 

Answer 1

While you have imported request , request.path should contain this information.

Answer 2

The first import request from a flask in your application. Then you can use it without going to the template:

 <li {%- if request.path == "/home" %} class="active"{% endif %}> <a href="/">Home</a> </li> <li {%- if request.path=="/about" %} class="active"{% endif %}> <a href="/about">About</a> </li> 

Answer 3

Using request.path does not seem to be the right approach, as you will have to update the paths if you change the URL rules or deploy your site under a subfolder.

Use request.url_rule.endpoint instead, it contains the actual name of the endpoint, independent of the actual path:

 (Pdb) request.url_rule.endpoint 'myblueprint.client_pipeline' 

In the template:

 <li {% if request.url_rule.endpoint == "myblueprint.client_pipeline" %}class="active"{% endif %}>Home</li> 

Good luck

Answer 4

To avoid using hard-coded URLs, you can use the url_for function as follows:

 {% for ni in ['index', 'foo', 'bar', 'baz'] %} <li {%- if request.path == url_for(ni) %} class="active"{% endif %}><a href="{{ url_for(ni) }}">{{ ni | capitalize }}</a></li> {% endfor %} 

In this case, index, foo, bar and baz will be the names of the functions that are used in your python code:

 @app.route('/') def index(): 

Answer 5

Try

 <li {% if request.endpoint == "blueprintname.routename" %}class="active"{% endif %}>Home</li> 

This worked for me.

Answer 6

You can also use .split if there is anything else in your url.

Example:

/
product / product / add
/ Product / 32432 / edit
/ Product / 32 432 / view

  {{request.path.split ('/') [1]}} 

This will return only the "product"
