使用不同的模板相同的對象

Question

我有一個顯示的位置列表中的一個模板：

list_of_locations.html

{% for loc in loc_list %} 
<p> 
    Total desks: {{loc.total_desks}} 
</p> 
<p> 
    Free desks: {{loc.free_desks}} 
</p> 
<p> 
    <a href="{% url 'cowork:offices:add' %}" class="btn btn-primary">Rent desk</a> 
</p> 

而且我已經得到了顯示窗體上添加一個辦公室另一個模板：

office_add.html：

<form class="form" method="POST" action="{% url 'cowork:offices:add' %}">{% csrf_token %} 
    {{ form.as_p }} 
    <input type="submit" value="Add" class="btn btn-primary" /> 
</form> 

型號：

class Location(models.Model): 
    city = models.CharField(max_length=200) 
    total_desks = models.IntegerField(verbose_name='Total desks') 
    reserved_desks = models.IntegerField(verbose_name='Reserved desks') 


class Desk(models.Model): 
    location = models.OneToOneField(Location, related_name='desks') 
    rent_start_date = models.DateTimeField(null=True) 
    rent_end_date = models.DateTimeField(null=True)Forms: 

class OfficeCreationForm(forms.ModelForm): 
    class Meta: 
     model = Desk 
     fields = ('location', 'rent_start_date', 'rent_end_date') 

瀏覽：

def search(request): 
    loc_list = Location.objects.all() 
    return render(request, 'list_of_locations.html', 'loc_list': loc_list) 

class OfficeAddView(UserMixin, views.LoginRequiredMixin, generic.FormView): 
    form_class = forms.OfficeCreationForm 
    template_name = "cowork/offices/company/office_add.html" 
    success_url = reverse_lazy('cowork:offices:list') 

    def form_valid(self, form): 
     self.object = form.save(commit=False) 
     self.object.company = self.user.companies.first() 
     self.object.owner = self.request.user 
     self.object.save() 
     return HttpResponseRedirect(self.get_success_url()) 

現在其對象由用戶選擇list_of_locations.html不管，用戶被要求選擇辦公桌office_add.html。我想改變它，以便當點擊list_of_locations.html中的特定對象時，用戶被重定向到office_add.html，但desk.location已被選中，當他/她保存表格時，desk.location將是用戶點擊的那個在list_of_locations.html。誰能幫忙？

Answer 1

只是改變list_of_locations.html到最後一行：

<a href="{% url 'cowork:offices:add' %}?location={{ loc.id }}" class="btn btn-primary">Rent desk</ai> 

此外，我想如果你在OfficeCreationForm禁用location域，以便用戶不能更改它這將是很好。
