Django url template tag refers to url with trailing question mark-CodePudding

This is a question concerning a trailing question mark that gets appended to the end of the URL rendered by Django's url template tag. My goal is to have this trailing question mark removed, yet I do not know how.

On my site's main page, I have a button - a form HTML tag, really - that directs me to another link of the website.

The form looks like:

<form action={% url 'my_index' %}>
   <input type="submit" value="some value" />
</form>

When clicking on that button, I am directed to the URL corresponding to the my_index view. The problem, however, is that at the end of that URL, there is a "/?" that is appended - that is, the URL is in the form "http://127.0.0.1:8000/my_app/?". I want to remove this /? at the end and also want to understand why this trailing question mark got appended.

My urls.py pointed to by the ROOT_URLCONF IS

urlpatterns = [
    path('', include('my_app.urls')),
]

And my urls.py within my_app app looks like:

urlpatterns = [
    path('', views.index, name='my_index'),
]

Any advice is appreciated.

CodePudding user response：

you are making an GET request (default for a form) with just a submit button but without an input value. After the ? you would normally see the input values that you send with the GET request like

http://127.0.0.1:8000/my_app/?my_value=12345

As your form is empty there is no parameter appended. You could use a

<a href='{% url 'my_index' %}'>

if you just want to call a page without any parameter

CodePudding user response：

You are sending an empty form. The default method of your form is GET. So the “?” is necessary to send the form...

Why don’t you use a normal link instead an empty form?
