Django @login_required causing issue when submitting forms
I am passing a some information to view function by submitting a form and view requires has @login_required decorator. Here is the template where i'm passing email ID using a from <form action="{% url 'become_booster' %}" method="post"> {% csrf_token %} <input type="hidden" name="email" value="{{ profile_user.email }}" /> <div class="form-group"> <div class="col-md-12 col-sm-12"> <input type="submit" class="btn btn-success btn-sm" value="Become a Booster"> </div> </div> </form> Here is the view function @login_required def become_booster(request): if request.method == "POST": email = request.POST.get('email') user = CustomUser.objects.filter(email= email)[0] tiers = Tiers.objects.filter(user=user) form = SubscriptionForm return render(request,'select_tier.html',{'tiers':tiers,'form':form}) This is working fine when the user logedin already. When user didn't login, @login_required sends them to login and when it comes back request.method is no longer POST. It no longer has that email info. Can someone help me with this. Thanks! -
django-summernote: how to get the created object by django?
I have a django form with a SummernoteInplaceWidget() and the summernote editor is correctly created. But i need to execute the following command to the editor: $('#summernote').summernote('editor.insertText', 'hello world'));, like the documentation (https://summernote.org/deep-dive/#basic-api). But this command doesn't work. I've tried this: $('#id_content').summernote('editor.insertText', 'hello world'); but other editor was created. I need to insert the text in the first editor that was created by django-summernote and don't create anymore. There is my form: class ParagrafoForm(ModelForm): content = forms.CharField(widget=SummernoteInplaceWidget()) There is my settings.py: SUMMERNOTE_CONFIG = { 'iframe': False, 'lang': 'pt-BR', 'toolbar': [ ['style', ['bold', 'italic', 'underline', 'strikethrough']], ['script', ['superscript', 'subscript']], ['clear', ['clear']], ['font', ['fontname', 'color']], ['para', ['ul', 'ol', 'paragraph', 'height']], ['table', ['table']], ['view', ['fullscreen', 'codeview', 'help']], ], 'disable_attachment': True, 'summernote': { 'width': '100%', 'height': '480', }, } In my template I've: {{ form.content|safe }} So, how to insert text in editor without creating anymore? Or how get the element in javascript to do this? Which's the identificator for the django-summernote created object? -

How can I make a Model field value unique (unique=True) but only comparing it to other models from that User?
I have a Tag model, that must have a name field that needs to be unique, but only for that user's tags. So that one user can't create two 'tagname' tags, but many different users can (create a tag with the same name). The field must be unique inside the models that relate to the User. This is the Model. class User(AbstractUser): email = models.EmailField(unique=True) class Tag(models.Model): name = models.CharField(max_length=30, unique=True) user = models.ForeignKey(User, null=True, on_delete=models.CASCADE, related_name='tags') -

In Home component of react+redux app, this.props.posts is undefined after calling action getPosts() on componentdidmount

infinite scrolling using django
I am fairly new to web development and I am building a blog style website. I use pagination to split posts into seperate pages but now i want to rather go for infinite scrolling like facebook does. I have watched countless videos and read a whole bunch of docs regarding this but to be honost, I get lost in all of them. I use django and python for my backend and all sources seem to use other languages etc like JS and ajax etc. All these mentioned sources start from the ground up which somehow confuses me as i already have pagination in place. Is there a way i can just tweak my current pagination to enable infinite scrolling instead of rebuilding the whole thing in different languages? or just help me get this done the right way. I've been struggling with this for weeks now so now i come here as a last resort. No point in running straight here if no effort was put in before hand Here is my current pagination code: views.py: from django.shortcuts import render, get_object_or_404 from .models import Post from django.views.generic import ListView, DetailView, CreateView, UpdateView, DeleteView from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin from django.contrib.auth.models … -

Link html page or jsp page to multiple django apps

I am using ModelChoiceField to retrieve from the model the data I need to display in the form (to let the users select from a scolldown menu). My query is complicate because need two filters based on variables passed by views I've tried to use the sessions but in form is not possible to import the session (based to my knowledge). form.py def __init__(self, pass_variables, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['initiative'] = forms.ModelChoiceField(queryset=raid_User_Initiative.objects.filter(company=pass_variables[1], username=pass_variables[0]).values_list('initiative', flat=True)) view.py pass_variables = ((str(request.user), companyname)) f = Issue_form(pass_variables) If I don't pass the variable the process works. The problem is with the code above as the form don't provide any error but it doesn't pass the if f.is_valid(): Thanks -
