Django: dynamically access queryset data from different models

I'm interested in learning how to display all attributes of a list of querysets that come from different models.



Here's an example:



models.py



class MyModelA(models.Model):
attr1 = something
attr2 = something

class MyModelB(models.Model):
attr3 = something
attr4 = something

class MyModelC(models.Model):
attr5 = something
attr6 = something


views.py



Let's say we have three model instances that are stored in a list:



all_selected_queries = [mymodela, mymodelb, mymodelc]


For each queryset in the list, I want to display all model field titles and data in a template.



My approach:



# Loop through the list and get the verbose name title of each field ("titel")

for z in all_selected_queries:
queryset_fields = z._meta.get_fields()
for f in queryset_fields:
titel = f.verbose_name.title()
return titel


What challenges me is how to get the fields' values without having to include the actual attribute name (because they are different for each queryset).



So instead of explictly calling



f.attr1, f.attr2, f.attr3, f.attr4, f.attr5


for each field, I'd like to encounter a solution that works across model boundaries.



Thank you very much for your help!

          You can try like this:



          v_list = list()
          for z in all_selected_queries:
          queryset_fields = z._meta.get_fields()
          values = dict()
          for f in queryset_fields:
          values[f.verbose_name.title()] = getattr(z, f.attname)
          v_list.append(values)
          return render(request,'some_template.html',{'values':v_list})


          And show them in template:



          {% for value in values %}
          {% for key, val in value.items %}
          <b>{{ key }}: </b>{{ val }}
          {% endfor %}
