Jsem začátečník v Pythonu a Django. Snažím se napsat jednoduchý Systém správy Nemovitostí. Mám problém s asigning stávající dům sdružení pro novou vlastnost vstupu. Moje soubory:
models.py
class Property(models.Model):
# Fields
id = models.AutoField(primary_key=True)
name = models.CharField(max_length=45, blank=False) # Property name
address = models.CharField(max_length=198, blank=False) # Property address
postalcode = models.CharField(max_length=6, blank=False) # Property postalcode
city = models.CharField(max_length=45, blank=False) # Property city
kw_number = models.CharField(max_length=15, blank=True) # Numer KW
ha_choice = models.CharField(max_length=2, choices=[(i.pk, i.name) for i in HousingAssociation.objects.all()])
# Foreign Keys
# TODO zmiana on_delete na inny!
house_association = models.ForeignKey(HousingAssociation, on_delete=models.CASCADE)
# Metadata
class Meta:
ordering = ['id']
# Methods
def add(self):
self.save()
def __str__(self):
"""String for representing the MyModelName object (in Admin site etc.)."""
# return self.id, self.name, self.address, self.postalcode, self.city, self.kw_number
return self.name
forms.py
class PropertyForm(forms.ModelForm):
class Meta:
model = Property
fields = ('name', 'address', 'postalcode', 'city', 'ha_choice', 'kw_number')
views.py
def property_form_new(request):
if request.method == "POST":
form = PropertyForm(request.POST)
if form.is_valid():
form.save()
return render(request, 'registration/prop/success.html')
else:
form = PropertyForm()
return render(request, 'registration/prop/prop_new.html', {'property_new': form})
V případě, že django se vrací na mě tohle: screenshot
To znamená Vybrat správnou možnost. 14 není mezi platné hodnoty.' 14 je id existující záznam v db a to je správné. Zdrojový kód HTML je takhle:
<h2>Nowa nieruchomość</h2>
<form method="POST" class="post-form">
<input type="hidden" name="csrfmiddlewaretoken" value="wsrMCEU8UfLMHCBGHtKfcI1wZzGdqM8HpEAEyexx2OIDZue8Chi4DaJxsLYg7aHk">

<p><label for="id_address">Address:</label> <input type="text" name="address" value="Batalionów Chłopskich 1/18" maxlength="198" required id="id_address"></p>

<p><label for="id_city">City:</label> <input type="text" name="city" value="Białystok" maxlength="45" required id="id_city"></p>
<ul class="errorlist"><li>Wybierz poprawną wartość. 14 nie jest żadną z dostępnych opcji.</li></ul>
<p><label for="id_ha_choice">Ha choice:</label> <select name="ha_choice" required id="id_ha_choice">
<option value="">---------</option>
<option value="14" selected>Spółdzielnia1</option>

</select></p>
<p><label for="id_kw_number">Kw number:</label>
<input type="text" name="kw_number" value="BI/1A/56743" maxlength="15" id="id_kw_number"></p>

</form>
Snažil jsem s
class PropertyForm(forms.ModelForm):
ha_choice = models.ChoiceField(choices=[(i.pk, i.name) for i in HousingAssociation.objects.all()])
class Meta:
model = Property
fields = ('name', 'address', 'postalcode', 'city', 'ha_choice', 'kw_number')
a také s MultipleChoiceField ale bez dobré účinky. Může někdo pomoci najít, jak asign to správně?
