Retrieving objects
I made a GET function that will retrieve posts and will make it available only to a particular user as well as its friends list. To make this work partially, I developed a raw query to get my desired output, and somehow it works fine for me. Now, I am trying to learn making queries in django without implementing raw query, so I am trying to maximize the Django ORM and not use raw query but I'm kinda stucked and kept wondering how I am gonna be able to make my queryset works without using raw query. this is my raw query: FeedMedia.objects.raw("""SELECT DISTINCT feed_media.* FROM feed_media INNER JOIN feed ON feed_media.feed_id = feed.id INNER JOIN media ON feed_media.media_id = media.id INNER JOIN profile ON profile.id = feed.profile_id INNER JOIN gosam_friend_profile ON gosam_friend_profile.profile_id = feed.profile_id INNER JOIN friendship_friend ON friendship_friend.id = gosam_friend_profile.gosam_friend_id WHERE friendship_friend.to_user_id = %(friend)s OR gosam_friend_profile.profile_id = %(profile)s""", params={'friend': request.user.pk, 'profile': profile.pk}) -

Django: Override form.errors messages on UserCreationForm
I'm trying to override (add languages) the messages of form.errors.

Display success message in Django after download
I am trying to trigger a download of an AWS S3 object using Django 3. views.py def pagelanding(request,slug): if some_condition: URL='URL_to_s3_file' return redirect(URL) So far everything works fine, when I trigger the condition in my template, the download is triggered.

Is there any way to trigger the download and display the message at the same time? -

Django schema explorer simple recursive algorithm - confused by results / how to fix
I am using Django and have a couple of use cases for which the ability for objects to trace their relationships through several models is required. I don't want to hand-code this functionality for every model. Some example models: class Project(models.Model): project_name = models.CharField(max_length=200, default="development_project") class Question(models.Model): project = models.ForeignKey(Project, default=1, on_delete=models.CASCADE) question_text = models.CharField(max_length=200, default="question text") class Extra(models.Model): extended_q = models.ForeignKey(Question, default=1, on_delete=models.CASCADE) summary_of = models.ForeignKey(Question, default=1, on_delete=models.CASCADE) content = models.CharField(max_length=200, default="simple summary") class Answer(models.Model): question = models.ForeignKey(Question, default=1, on_delete=models.CASCADE) user = models.ForeignKey(User, default=1, on_delete=models.CASCADE) Using models as nodes of a network and relationships as edges, this seems like it should be manageable, but for some complexity where there are 'redundant' edges - do we permit an Extra to summarise Answers from a different project? my use cases will be: a models.Manager class that can act as the default manager for a sub-class of Django apps that work together in a unified site and help do the sort of row-separating management that will keep users, even in the admin, from getting under each others feet. an overall app using ContentTypes that can help the user build datasets and organise tables for dataframes (taking fks and making them appropriate category … -
Label and input value overlaps with django-material and datepicker
So the idea is that I need a pop-up and in that pop-up there should be a form in which you have to choose the date, so the pop-up have a Form object with a TextField that emulates the a date input to use the datepicker of material, the problem comes with the label of that input that overlaps with the input itself like this. I tried using javascript to add the class "active" to the label when you click the input because that is what triggers the label to go up but it doesn't recognize it and doesnt apply the class. The html renders like this: <div class="input-field col s12 required" id="id_fecha_cobro_container"> <i class="material-icons prefix">insert_invitation</i><input id="id_fecha_cobro" name="fecha_cobro" type="date"> <label for="id_fecha_cobro">Fecha de Cobro</label> </div> This is the modal in django: {% block change_form %} {% form %} {% part form.fecha_cobro prefix %}<i class="material-icons prefix">insert_invitation</i>{% endpart %} {% endform %} {% prepopulated_fields_js %} {% endblock %} This is the form class: class AvisoVacacionForm(forms.Form): fecha_cobro = forms.DateField(label="Fecha de Cobro", required=True, widget=forms.TextInput(attrs={'type': 'date'})) def __init__(self, *args, **kwargs): super(AvisoVacacionForm, self).__init__(*args, **kwargs) This is what I've tried using javascript: $('#id_fecha_cobro').click(function(){ $("label[for='id_fecha_cobro']").addClass("active") });
