hello I have a table named Exercise data where I pass data from form and save them in the db, my problem is that I have more same objects to save inside the db but I don't know how to do it.
I left you my views.py file where you can find the code I created.
I read around that I should use the create_bulk but I don't understand how I can pass it some data from my form, could someone help me please? =)
views.py

def creaScheda(request):
if request.method == "POST":
form = CreaSchedaForm(request.POST)
if form.is_valid():
schedaName = form.cleaned_data['nome_scheda']
scheda = form.save(commit = False)
scheda.utente = request.user
scheda.save()
gruppi = DatiGruppi(
giorni_settimana = form.cleaned_data['giorni_settimana'],
dati_gruppo = form.cleaned_data['dati_gruppo'],
gruppi_scheda = Schede.objects.get(nome_scheda = schedaName)
)
gruppi.save()
esercizi = DatiEsercizi(

peso = form.cleaned_data['peso'],
gruppo_single = DatiGruppi.objects.get(gruppi_scheda = scheda.id),
dati_esercizio = form.cleaned_data['dati_esercizio']

#esercizi.save()

I have this view that creates a form with groups and exercises.
How can I do to be able to create more groups and exercises in the template?
views.py
#login_required
def creaScheda(request):
if request.method == "POST":
form = CreaSchedaForm(request.POST)
if form.is_valid():
schedaName = form.cleaned_data['nome_scheda']
scheda = form.save(commit = False)
scheda.utente = request.user
scheda.save()
gruppi = DatiGruppi(
giorni_settimana = form.cleaned_data['giorni_settimana'],
dati_gruppo = form.cleaned_data['dati_gruppo'],
gruppi_scheda = Schede.objects.get(nome_scheda = schedaName)
)
gruppi.save()
esercizi = DatiEsercizi(
serie = form.cleaned_data['serie'],
ripetizione = form.cleaned_data['ripetizione'],
peso = form.cleaned_data['peso'],
gruppo_single = DatiGruppi.objects.get(gruppi_scheda = scheda.id),
dati_esercizio = form.cleaned_data['dati_esercizio']
)
esercizi.save()
return redirect('/backoffice')
else:
form = CreaSchedaForm()
context = {"form": form}
return render(request, "crea_scheda.html", context)
A solution to this would be using the bulk_create method on the object manager with an array/list of the objects to be created
example
ModelName.objects.bulk_create([
ModelName(title="Model1"),
ModelName(title="Model2"),
ModelName(title="Model3"),
])
where ModelName refers to the Name of Your Model, and ModelName within the list refers to the different instances/records of the ModelName class/database to be create in a bulk
I have a crud application and would like to update the items. I have checked some solutions online which explains that the .update method can't be used like this but for only a queryset. I don't know how to update the information manually. Thanks
views.py
def UpdateReservation(request, pk):
table_exists = Reservation.objects.get(id=pk)
form = ReservationForm(instance=table_exists)
if request.method == "POST":
if request.POST['table']:
request.POST = request.POST.copy()
table_exists = Reservation.objects.get(id=pk)
try:
if table_exists:
time = form['time']
people = form['people']
comment = form['comment']
date_reserved = form['date_reserved']
email = form['email']
phone = form['phone']
first_name = form['first_name']
resrv = table_exists.update(email=email, first_name=first_name, people=people, time=time, date_reserved=date_reserved, comment=comment, table=table_exists)
resrv.save()
messages.success(request, "you have successfully edited.")
return redirect(request.path)
else:
messages.error(request, "Unable to edit.")
return redirect(request.path)
except Exception as e:
messages.error(request, "Unknown error" + str(e))
return redirect(request.path)
context = {"form":form}
return render(request, "dashboard/super/admin/update_reserve.html", context)
After trying that, it returns the error, Unknown error'Reservation' object has no attribute 'update'
It is better to validate the form and update the individual fields with respective values and then save the object. The view should be as follows:
from django.shortcuts import get_object_or_404
def UpdateReservation(request, pk):
table_exists = get_object_or_404(Reservation, id=pk)
form = ReservationForm(instance=table_exists)
if request.method == "POST":
form = ReservationForm(request.POST, instance=table_exists)
if form.is_valid():
time = form['time']
people = form['people']
comment = form['comment']
date_reserved = form['date_reserved']
email = form['email']
phone = form['phone']
first_name = form['first_name']
table_exists.email = email
table_exists.first_name = first_name
table_exists.people = people
table_exists.time = time
table_exists.date_reserved = date_reserved
table_exists.comment = comment
table_exists.save()
messages.success(request, "you have successfully edited.")
return redirect(request.path)
else:
messages.error(request, "Unable to edit.")
return redirect(request.path)
context = {"form": form}
return render(request, "dashboard/super/admin/update_reserve.html", context)
You should use model like this:
table_exists = Reservation.objects.get(id=pk)
table_exists.email = email
table_exists.first_name = first_name
table_exists.people = people
table_exists.time = time
table_exists.date_reserved = date_reserved
table_exists.comment = comment
table_exists.table = table_exists
table_exists.save()
i have a small form in my blog detail view and it has a name,last name,email and an image field. the first three work fine but when i add the imagefield in the form, the form wont save from the page but it works from admin page.
this is my views.py:
def campaign_detail_view(request, id):
template_name = 'gngo/campaign-detail.html'
campaign = get_object_or_404(Campaign, id = id)
comments = CampaignForm.objects.filter(campaign=campaign).order_by('-id')
form = FormCamp(request.POST)
if request.method == 'POST':
if form.is_valid():
name = request.POST.get('name')
last = request.POST.get('last')
email = request.POST.get('email')
comment = CampaignForm.objects.create(campaign=campaign,name=name,last=last,email=email)
comment.save()
return redirect('campaign-detail',id=id)
else:
form = FormCamp()
context = {
'campaign':campaign,
'comments':comments,
'form':form,
}
context["object"] = Campaign.objects.get(id = id)
return render(request, template_name, context)
and this is my comment model:
class CampaignForm(models.Model):
campaign = models.ForeignKey(Campaign, on_delete=models.CASCADE)
name = models.CharField(max_length=100)
last = models.CharField(max_length=100)
email = models.EmailField()
image = models.ImageField(upload_to='images')
this is a non user form, so everyone can fill it. please help me understand how to add the ability to upload an image in this form
oh and this the form:
class FormCamp(forms.ModelForm):
class Meta:
model = CampaignForm
fields = ('name','last','email', 'image',)
THANKS ALOT FOR THE ANSWERS AND SUPPORTS
Instead of using the form to validate and then manually extracting the fields again, you should use the save method of your ModelForm and pass request.FILES to your form when creating it.
And as the campaign is not an editable field, it shall be added after creating the object.
def campaign_detail_view(request, id):
template_name = 'gngo/campaign-detail.html'
campaign = get_object_or_404(Campaign, id = id)
comments = CampaignForm.objects.filter(campaign=campaign).order_by('-id')
if request.method == 'POST':
form = FormCamp(request.POST, request.FILES)
if form.is_valid():
campaign_form = form.save(commit=False)
campaign_form.campaign = campaign
campaign_form.save()
return redirect('campaign-detail',id=id)
else:
form = FormCamp()
context = {
'campaign':campaign,
'comments':comments,
'form':form,
}
context["object"] = Campaign.objects.get(id = id)
return render(request, template_name, context)
https://docs.djangoproject.com/en/2.2/topics/forms/modelforms/#the-save-method
https://docs.djangoproject.com/en/2.2/topics/forms/#the-view
Try this:
def campaign_detail_view(request, id):
template_name = 'gngo/campaign-detail.html'
campaign = get_object_or_404(Campaign, id = id)
comments = CampaignForm.objects.filter(campaign=campaign).order_by('-id')
form = FormCamp(request.POST, request.FILES)
if request.method == 'POST':
if form.is_valid():
comment = form.save(commit=False)
comment = CampaignForm.objects.create(campaign=campaign,name=name,last=last,email=email)
comment = request.FILES['image']
comment.save()
return redirect('campaign-detail',id=id)
else:
form = FormCamp()
context = {
'campaign':campaign,
'comments':comments,
'form':form,
}
context["object"] = Campaign.objects.get(id = id)
return render(request, template_name, context)
class FormCamp(forms.ModelForm): to this;
class FormCamp(forms.Form):
Don't forget to add enctype=multipart/form-data in your form in template.

after i populate the form and submit it, the view didn't update the database instance,why?
i can do it one by one in shell as below.
new confuse!when i populate the form with invalid value,for example, an inexistent id of Patient object,it will still render the template,why?
It seems to me your problem is that you never reach the code under the if form.is_valid() of your patient_num view. Try to add some prints after the if form.is_valid() clause and make sure your form is valid. It is expected that your model will not be updated if your form is not valid.
Your problem here that you are passing request to form instead request.POST
form = EditToBeSaveForm(request.POST)
i put some 'print stuff' in my view and disvocer sth:
def patient_num(request):
print(111)
if request.method == 'POST':
print(2222)
form = EditToBeSaveForm(request.POST)
if form.is_valid():
print(3333)
num = form.cleaned_data['病人编号']
new_p = Patient.objects.get(p_number=num)
if new_p:
print(4444)
new_p.p_name = form.cleaned_data['姓名']
new_p.p_sex = form.cleaned_data['性别']
new_p.p_age = form.cleaned_data['年龄']
new_p.p_tel_number = form.cleaned_data['电话号码']
new_p.save()
return render(request, 'polls/patient_edit.html')
else:
form = EditToBeSaveForm()
return render(request, 'polls/patient_num.html', {'form': form})
i can only see 111 in the shell output.it seems that the view even didn't receive the post request.and i check my html file and find the problem.the form's destination direct to another view function…… it's so stupid, i'm sorry for waste your time !
I made a simple pet store app and just added search box feature and I received this error
ValueError at /pet/search/
The view mysite.pet.views.search_page didn't return an HttpResponse object.
I tried to change render_to_response into HttpResponseRedirect but still got the same error.
Linking back to my search_page function in views.
def search_page(request):
form = SearchForm()
if request.method == "POST":
f = SearchForm(request.POST)
if f.is_valid():
Pets = Pet.objects.filter(animal = f.cleaned_data["text"])
return HttpResponseRedirect("search.html",{"Pets":Pets},{"form":form})
else:
return render_to_response("search.html",{"form":form} , context_instance = RequestContext(request))
I did some research and I understand a view has to return a HttpResponse when a HttpRequest is made and render_to_response is just a shortcut.Can someone help explain why this function won't work.Thank you
You are getting this problem because you havn't written a HttpResponse object if request type is not POST
To overcome this in your view write somthing which will process if request type is not post
def search_page(request):
form = SearchForm()
if request.method == "POST":
f = SearchForm(request.POST)
if f.is_valid():
Pets = Pet.objects.filter(animal = f.cleaned_data["text"])
return HttpResponseRedirect("search.html",{"Pets":Pets},{"form":form})
return render_to_response("search.html",{"form":form} , context_instance = RequestContext(request))
Hope this will help you thanks
The error is because when the function is called the method type is not POST and it does not find the corresponding HttpResponse object.
def search_page(request):
form = SearchForm()
if request.method == "POST":
f = SearchForm(request.POST)
if f.is_valid():
Pets = Pet.objects.filter(animal = f.cleaned_data["text"])
return HttpResponseRedirect("search.html",{"Pets":Pets},{"form":form})
else:
return render_to_response("search.html",{"form":form} , context_instance = RequestContext(request))
return render_to_response("any.html",{} , context_instance = RequestContext(request))
