show forms for model who can have multiple instance
I am creating a simple project which is about creating a resume by user. In resume, a user can have multiple experience, educational background and etc. That is why I have created the following table where experience, educational background, skills are foreignkey to the resume table. class Resume(models.Model): applicant = models.OneToOneField(User, on_delete=models.CASCADE) name = models.CharField(max_length=100, blank=False, null=False, help_text="Full Name") slug = models.SlugField(max_length=50, unique=True) designation = models.CharField(max_length=200, blank=True, null=True) city = models.CharField(max_length=100, blank=True, null=True) def __str__(self): return self.name class Education(models.Model): resume = models.ForeignKey(Resume, related_name='education') name = models.CharField(max_length=100, blank=False, null=False, help_text="Name of an institution") course = models.CharField(max_length=200, blank=False, null=False, help_text="Name of a course") description = models.CharField(max_length=400, blank=True, null=True) start_date = models.DateField() end_date = models.DateField() class Experience(models.Model): resume = models.ForeignKey(Resume, related_name='experience') designation = models.CharField(max_length=100, blank=True, null=True) company = models.CharField(max_length=100, blank=True, null=True) description=models.CharField(max_length=400, blank=True, null=True) start_date = models.DateField() end_date = models.DateField() class Skill(models.Model): resume=models.ForeignKey(Resume, related_name="skills") name = models.CharField(max_length=100, blank=True, null=True, help_text="Name of the skill") class Meta: verbose_name='Skill' verbose_name_plural='Skills' def __str__(self): return self.name Now for such situation, do I have to create a ResumeForm, EducationForm, ExperienceForm etc and create an Education, Experience and Skill formset or I have to do something else. I do not have clear idea on how to move forward now for … -
django - Ajax Live Search, What Am I Doing Wrong?
I'm trying to have a live search feature where as soon as you type something in a search box, the results automatically appear right below. I've been following this tutorial with no luck. Nothing seems to be happening when I type a query. Could anybody tell me what I'm doing wrong? urls.py urlpatterns = [ url(r'^$', views.list_of_post, name='list_of_post'), [...] url(r'^search/$', views.search_titles), ] # this is my blog app views.

Django test Client submitting a form with a POST request
How can I submit a POST request with Django test Client, such that I include form data in it? In particular, I would like to have something like (inspired by How should I write tests for Forms in Django?): from django.tests import TestCase class MyTests(TestCase): def test_forms(self): response = self.client.post("/my/form/", {'something':'something'}) My endpoint /my/form has some internal logic to deal with 'something'. The problem was that when trying to later access request.POST.get('something') I couldn't get anything. I found a solution so I'm sharing below. -
'NoneType' object has no attribute '__getitem__' On Template Render
I know there are questions already answering this but they all seem specific to the project. I have tried to create a MultiValueField, starting with a more complex one and dumbed it down a little to make it easier to understand and implement. So i thought i did it. But now I’m getting 'NoneType' object has no attribute '__getitem__' So first thing is the MultiValueField that has to be a sub class of a MultiWidget class. class LeadTimeWidget(MultiWidget): def __init__(self, attrs=None): widget = [forms.TextInput(), forms.TextInput()] super(LeadTimeWidget, self).__init__(widget, attrs) def decompress(self, value): if value: return value class LeadTimeMultiField(MultiValueField): widget = LeadTimeWidget def __init__(self, *args, **kwargs): list_fields = [forms.fields.CharField(max_length=31), forms.fields.CharField(max_length=31)] super(LeadTimeMultiField, self).__init__(list_fields, *args, **kwargs) def compress(self, data_list): pass After that its conecting the MultiValueField to the form... class AssessmentForm(FrontEndForm): new_price = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) used_price = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) repair_price = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) exchange_price = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) other_label = forms.CharField(required=False) lead_time = LeadTimeMultiField() other_price = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) quote_note = forms.CharField(required=False, widget=widgets.Textarea(attrs={"rows": 3, "cols": 50})) inbound_shipping_cost = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) outbound_shipping_cost = forms.DecimalField(max_digits=10, decimal_places=2, required=False, widget=MoneyInput) You can see that i have done that lead_time = LeadTimeMultiField(), The next bit would be to render … -

If statement in my Django template...Is there a better way?
In my Django template: I'm trying to add an extra div around my for loop only if the length of the data being passed to the template is 3. This is what I'm trying right now but it seems like there could be better way than doing two if statements to check for the length: {% if items|length == 3 %} <div class='three-item-wrap'> {% endif %} {% for item in items %} ....... {% endfor %} {% if items|length == 3 %} </div> //close .three-item-wrap {% endif %} -
Loosing timezone on data retrieval over objects
I have a model which has a DateTimeField for a start date. When I'm creating new objects of the model and store them in the postgre database the given timezone is 'Europe/Berlin'. I confirmed it just before calling save() and the entries have the correct offsets in the database. The timezone of the database also matches with the timezone of the objects. But when I retrieve objects of the model over .filter() the timezone is set to 'UTC', so I'm loosing the timezone. Of course it should be 'Europe/Berlin' as well. Inside settings.py is also the correct timezone TIME_ZONE = 'Europe/Berlin' Can anybody help me? -

Webpage that imports data, process data with a script and exports data visualisation as pdf or docx
I'm currently working on a webpage where I want to have an application that can through an import button import a csv-file. Then behind the scenes I want to process the data, e.g. using a Python script, and through that get some data visualizations. These data visualizations should be displayed on the webpage combined with a text field, where the user can enter the interpretation of the data visualizations. Finally, the user should be able to export the data visualizations combined with his/her interpretation in a report as a pdf- og docx-file. Currently, I'm using the Python web framework, Django, since it is based on Python and might co-operate better with Python scripts. However, I'm still a bit unsure if this framework is able to do what I want. Does any of you have any experience with importing csv-files, generating data visualizations and exporting pdf's or docx's in Django or would you recommend another framework maybe based on another language? Looking forward to get some feedback plus validation or invalidation of my first steps towards my goal! -

Why dispatch method is taking long time to call target method in Django Rest Framework?

Django save base64 string to filesystem using models.ImageField
I am trying to upload image to file system using python django. I dont have any idea on how to proceed further. in my model.py: Class Test(object): mission = models.TextField(blank=True) image = models.ImageField(upload_to='documents/images/',blank=True) account = models.OneToOneField(Account, related_name='account') in my view.py def add_image(request, account): req = get_request_json(request) data = Test.objects.add_image(account, req) in my manager.py Class TestManager(models.Manager): def add_image(self, account, input): acc = self.get(account=account) acc.save() return acc; But I am not sure how to proceed from here. I would like to know how to save the base64 image string to the specified location and store the path/file name in database? I have worked with python where I write the files to a directory and get the path and store in db. Here I want to use the django options. I have to repeat the same process with other file formats too.
