Django: Attributes Not Being Applied to Form
As the title states I have a django form that I am trying to customize yet for some reason the attributes are not being applied to it. I have used the exact same code in other projects and it worked perfectly except now for some reason it is not. The only other question I have found by googling is this one question. I have the exact same issue as this, I am trying to inject attributes into my label field but for what ever reason it is not working no matter what I have tried. My code is as follows: class MyAuthenticationForm(AuthenticationForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['username'].widget = forms.widgets.TextInput(attrs={ 'class': 'form-control' }) self.fields['password'].widget = forms.widgets.PasswordInput(attrs={ 'class': 'form-control' }) The weirdest thing was when I first started coding this morning it worked, then every subsequent time I visited my form it stopped. I truly have no idea what is going on and why this isn't working. Any help is greatly appreciated! -
how to use jquery selector to select id of django template variable value?
I have a django web app. In the html page, some element id in the for loop used django template variable value, as in the for loop every line should have different id value. But in the below jquery, when I tried to use selector, the django template variable value could not be selected(obj.title here in my case). <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script> {% for obj in query_results_book %} <td> <select name="keep_discard" id="keep_discard" onchange="GetVal(this)"> <option value="Keep">Keep</option> <option value="Discard">Discard</option> </select> <select name="discard_reason" id="{{obj.title}}"> <option value="Change edition">Change edition</option> <option value="Change to eTextbook">Change to eTextbook</option> <option value="Change title">Change title</option> <option value="No material required">No material required</option> </select> </td> {%endfor%} <script> function GetVal(obj){ var index = obj.selectedIndex; if(index == 1){ $("#obj.title").show(); } else{ $("#obj.title ").hide(); } } </script> Now the js script could not work for the query selector, it does not select my element. How could I let the jquery selector select some id, which is my django template variable value? -

The instance param of the signal is of course the MyModel instance.
