Im learning Django and get stuck with this problem. I need to list "users" with their respective data to an html list. I tried but there is no list generated. Already have my db populated with 100 lines.
This is my models.py
from django.db import models
# Create your models here.
class General(models.Model):
id = models.CharField(max_length=128, primary_key=True)
name= models.CharField(max_length=128)
lastname= models.CharField(max_length=128)
state= models.CharField(max_length=128)
asd= models.CharField(max_length=128)
spc= models.CharField(max_length=128)
dot = models.CharField(max_length=128, blank=True)
def __str__(self):
return self.name
This is my views.py, already tried return render_to_response
, and tried to use General.objects.all()/General.objects.get()
but it says
General has no objects
so i cant make the dictionary manually
from django.shortcuts import render
from Myapp.models import General
from django.forms.models import model_to_dict
# Create your views here.
def VisualizadorGeneral(request):
listaGeneralDic = model_to_dict(General)
return render(request, "VisualizadorGeneral.html", context=listaGeneralDic)
And this is my HTML:
<div class="container">
{% if listaGeneralDic %}
<table class="table table-bordered table-hover">
<thead>
<tr>
<th>id</th>
<th>name</th>
<th>lastname</th>
<th>state</th>
<th>asd</th>
<th>spc</th>
<th>dot</th>
</tr>
</thead>
<tbody>
{% for dato in listaGeneralDic %}
<tr>
<td scope="row">{{ dato.id }}</td>
<td>{{ dato.name }}</td>
<td>{{ dato.lastname }}</td>
<td>{{ dato.state }}</td>
<td>{{ dato.asd }}</td>
<td>{{ dato.spc }}</td>
<td>{{ dato.dot }}</td>
</tr>
{% endfor %}
</tbody>
{% else %}
<p>Nothing to see</p>
{% endif %}
</table>
</div>
Someone can spot what im doing wrong?I was been 3 days lurking the whole internet to find answers.
A class is a "blueprint" that can be used to "instantiate" different "objects". It only specifies the different properties and methods. But in template we need to show a list of real objects.
def VisualizadorGeneral(request):
objects_list = General.objects.all() # here we are retrieving real instances
list_of_object_dicts = [model_to_dict(obj) for obj in objects_list] # and in this row we are applying function model_to_dict for each object
context_data = {"listaGeneralDic: list_of_object_dicts} # context should be a dict with keys and values, after announcing "listaGeneralDic" in context we will be able to call it in template
return render(request, "VisualizadorGeneral.html", context=context_data)
You can also use Django's class-based List View
to have all the General data objects shoved to the template as a context object for you. It will also take care of rendering and get/post for you
from django.views.generic import ListView
class VisualizadorGeneral(ListView)
template_name = '<your_template_name>'
model = General
context_object_name = 'dto'
# this is the name you will refer to the object in the template
you can refer to in your template like this
{% for item in dto %}
<td>{{ item.<whatever> }}</td>
{% endfor %}
