Need help in Django templates
So I have a list named counts and it has a method times_used. I cannot use the method on the counts but it can be only used on each item in the list counts. The problem now is I cannot use counts[0].times_used in html template as it shows the error of not parsing. So I have used {% for count in counts %} <td>{{ count.times_used }}</td> {% endfor %} The problem here is all count.times_used is displayed for every item in counts. I want the count to be displayed only once per loop based on loop number (like counts[0],counts[1]....). How can I do this? -

Need help using placeholders for auth_views in django
I created a forgot password functionality using django.contrib.auth.views which is working fine. However the styling does not go with the rest of the site. I want to use only placeholders for the form fields. But since I am using the mentioned view, i don't know how. I want to remove the Email label here and write that as a placeholder This is the general theme of the site: For the login and register pages, I am mentioning the fields separately as shown in the figure: If i try do that for my forgot-password page, I get this result with no visible fields. If I try using form.password1 and form.password2, it doesn't work and I don't get the form fields at all. Here i use only the form option. I want to have the labels as placeholders(no labels). And the other stuff removed. Here are the views used in the urls.py file: Is the view using the second form? Also is there an option for a redirect here so I can just redirect my users to login page instead of a separate page? please help -

update the choice list of django model using django Admin panel
my model is currently as follows : class Food(model.Model): CUISINE_CHOICES = ( ('1', 'Chinese'), ('2', 'French'), ('3', 'Italian'), ('4', 'Indian'), ('5', 'Japanese'), ('6', 'Moroccan'), ('7', 'Spanish'), ('8', 'Thai'), ) Cuisine = models.CharField(max_length = 20,choices = CUISINE_CHOICES,default = '1') Dish = models.CharField(max_length=200, blank=True) Is there a way by which I can update the CUISINE_CHOICES list in future from the admin panel. Say I need to add Arabian as the 9th cuisine. I know that manually updating the cuisine_choices list will resolve it, I want to know if i can do the same from Admin Panel. If yes, How ? I've searched for similar questions/ solutions but could not find one that matches my requirement. TIA. -
Inlineformset_factory saving parent without child and not displaying validation errors if child is none
I am having 2 issues, one if you submit and click back and then submit again it duplicates the instance in the database - in this case Household. In addition it is saving the parent 'Household' without the child 'Applicants' despite me setting min_num=1 can someone point me in the right direction to resolve this issue.
