Django. Star rating multiple form displayed in a grid view not working
I've got a little problem. I have a page that is used to rate ski resorts. They are displayed in a grid view and each resort has a star rating form beneath. The problem is that only the first item in the grid can be rated. I tried to assign each form an unique id but that didn't work. Here is the code: class AddRatingForm(forms.ModelForm): class Meta: model = ResortUserRating fields = '__all__' widgets = { 'resort_rating': forms.RadioSelect() } def __init__(self, pk, *args, **kwargs): super(AddRatingForm, self).__init__(*args, **kwargs) self.pk = pk self.fields['user'].initial = self.pk def clean(self): return self.cleaned_data {% for resort in dashboard_resorts %} <div class = "grid-item"> {% if resort.img %} <img class="card-img-top" src="{{resort.img.url}}" alt ="Card image cap" height="300px" width="380px"> {% endif %} <p> <b>{{resort.name|upper}} </b></p> <p> <b>{{resort.id|upper}} </b></p> <form method="post" action = "{% url 'aplicatie2:rating' %}"> {% csrf_token %} <input type = "hidden" name = "user" value = "{{user.id}}"> <input type = "hidden" name = "resorts" value = " {{resort.id}}"> <div class="rate"> <input type="radio" name="resort_rating" id="rating1" value="1" required /><label for="rating1" title="1"> </label> <input type="radio" name="resort_rating" id="rating2" value="2" required /><label for="rating2" title="2"> </label> <input type="radio" name="resort_rating" id="rating3" value="3" required /><label for="rating3" title="3"> </label> <input type="radio" name="resort_rating" id="rating4" value="4" required /><label … -
django submit multiple forms
have concocted the following so far. pretty sure its sloppy code, but its meant for some crude maintenance and seems to work up to the point i would like it to work. point is i get a long list of forms, i can use Ajax to select them them all or assign them all to the category all at once, that is exactly what i want. what i can not figure out however is to submit all these forms in one go, the code as is works that i can submit 1. but just like the select all and categorize all code, after selecting those i also would like to SUBMIT ALL <script language="JavaScript"> function toggle(source) { checkboxes = document.getElementsByName('blockbutton'); for(var i=0, n=checkboxes.length;i<n;i++) { checkboxes[i].checked = source.checked; } } </script> <script language="javascript"> function setDropDown() { var index_name = document.getElementsByName('ForceSelection')[0].selectedIndex; var others = document.getElementsByName('Qualifications'); for (i = 0; i < others.length; i++) others[i].selectedIndex = index_name; } </script> <input type="checkbox" onClick="toggle(this)" /> Toggle All<br/> <select name="ForceSelection" id="ForceSelection" onChange="javascript:return setDropDown();"> <option value="" selected="selected">Select Category</option> {% for category in categories %} <optgroup label="{{ category.name }}"> {% for item in category.subcategory_set.all %} <option val="{{ item.name }}"> {{ item.name }} </option> {% endfor %} </optgroup> {% … -

How to quickly reset Django DB after changes?
I'm often experimenting around creating different models, changing relations and so forth. This usually happens when starting a new project. At this phase I do not want to create any migrations but instead just get the thing up and running. So i very often do this: rm db.sqlite3 rm -r project/apps/app/migrations/* python manage.py makemigrations app python manage.py migrate app python manage.py createsuperuser bla bla Is there any way to have this "reset" function more quickly? I frustratingly found out, that django does not allow superusers to be created by a shell script. Is there any way to purge the db without removing the users? How do you do this? -

How to limit the number of responses to my for loop to 3 in Django Templates?
In my current Django template I have two models in use, which are defined in my views.py as: 'tasks' : IndividualTask.objects.all(), 'updates' : TaskUpdate.objects.all(), I have set up signals so that when there is an update to a task, an update is created. Currently, I iterate through each task, then each of their updates and pull out the relevant updates for each task, as shown below. {% for task in tasks %} {% for update in updates %} {% if task.id == update.task.id %} {{ update.update }} {% endif %} {% endfor %} {% endfor %} However, I would like to limit the number of updates I show to three. I have tried using slice, show below, but this limits all updates to the top 3 of all updates as opposed to the top 3 of each individual task's updates. {% for task in tasks %} {% for update in updates|slice:":3" %} {% if task.id == update.task.id %} {{ update.update }} {% endif %} {% endfor %} {% endfor %} I would be grateful for any advice as to how I can limit the number of updates shown for each task to 3 please? -

How to use toastr in django to display messages

Form post data is not passing back to html file in django

type object is not subscriptable - I understand the error, but I don't know why it happens
Disclaimer: this code worked on python 2.7, I just migrated to 3.7 :) The error that's happening does happen in Django 1.11 I have this line of code which throws me the 'type object is not subscriptable' error: from ..settings import Settings skinurl = join(url_base, 'css/skins/skin-%s.min.css' % Settings['THEME.SKIN']) The settings class is this: class Settings(SettingsBase): store = DEFAULT_SETTINGS __metaclass__ = Meta def __getitem__(self, key): print(self.store['THEME.SKIN']) return self.iget(key) in DEFAULT_SETTINGS, I have THEME.SKIN: 'THEME': { 'SKIN': 'green', }, I have an idea why it might happen - that print in getitem doesn't return anything. If I change it to print(self.store['THEME']['SKIN']) it does, though. If I also change that join call to this skinurl = join(url_base, 'css/skins/skin-%s.min.css' % Settings['THEME']['SKIN']) I still get type object is not subscriptable.

DRF add computed field based on requesting user
I have a model which has specific many to many fields to the user model. Now, to prevent information leaking, I do not want to return the whole related field though the rest framework. But, I want to create some kind of computed field, such that it return True if the requesting user is in the related field, and False otherwise. Is there a way to make this work? For example, as it stands now, the rest framework will list the users for "user_like" and "user_bookmark", which I dont want to happen, hence I want to exclude them from the serialized. But I want to have a field, say, named is_liked, which will be true if request.user is in user_like, and false otherwise.
