I am new to django and developing a small app in which i have to update a Project Model. I am using django builtin UpdateView to update the details of a project already saved. I am also using widget_tweaks to render fields with custom bootstrap classes for styling. When i run this code it shows str object has no attribute 'as_widget Error. I think the form fields are going to the template as a string not as an object and render_field tag of widget tweak is unable to render it, but i don't know why it is going as a string?. I only want to update certain fields of the model. that's why I've used "fields" in UpdateView. But I also tried form_class just to check but that didn't work either. I've been stuck on this bug for two days. Any help will be appreciated.
Following is the project Model
class Project(models.Model):
id = models.BigAutoField(primary_key=True)
name = models.CharField(max_length=20 , unique=True)
startDate = models.DateField(default=timezone.now)
endDate = models.DateField()
sourceOfProject = models.CharField(default='Website', verbose_name='Project Source',max_length=20 , choices=(('Website' , 'Website'),('Client','Client'))) # website or client etc
sourceName = models.CharField(default='' , verbose_name='Source Name' , max_length=20)
paymentType = models.CharField(default='Fixed' , verbose_name='Payment Type', max_length=20 , choices=(('Hourly','Hourly'),('Fixed','Fixed'))) # If True then hourly else fixed
ProjectPaymentAmount = models.PositiveIntegerField(verbose_name='Amount') # this amount is according to hourlyPayment==True or False
is_Active = models.BooleanField(default=True)
projectSeverity = models.PositiveIntegerField(default=1, choices=SEVERITY_CHOICES)
hubstaffName = models.CharField(max_length=30, null=True , default='')
hoursToWork = models.PositiveIntegerField()
def __str__(self):
return "Project: {}".format(self.name)
Here is the view
class ProjectUpdateView(UpdateView):
model = Project
fields = ('hubstaffName','endDate', 'hoursToWork' ,'paymentType','ProjectPaymentAmount','sourceOfProject','sourceName',)
#form_class = ProjectForm
template_name = "Administration/Manage-Projects.html"
context_object_name = 'project_form' #name of the context object in the template
pk_url_kwarg = 'pid'
following is the urls part.
path('edit-Project/<int:pid>',ProjectUpdateView.as_view(),name='editProject')
On this button click it post this form to 'Administration:editProject' view where I am using Update View.
<form action="{% url 'Administration:editProject' pid %}" method="post">
{% csrf_token %}
<button id="EditProject" type="submit" class="btn btn-primary mx-3 my-2" >Edit this Project</button>
</form>
Following is the edit template I am using to edit Project.
{% extends 'base.html' %}
{% load widget_tweaks %}
{% block content %}
