django - 如何在表单中设置初始值

问题描述

嘿伙计们，我如何在表单字段中设置初始值，假设用户在搜索表单中单击“BidForm”，我希望 BidForm 值将是其他表单中 ProjectName 的值...

这是我的搜索视图中的代码

def search_views(request):
    project_list = ProjectNameInviToBid.objects.all()
    query = request.GET.get('query')
    if query:
        project_list = project_list.filter(ProjectName__icontains=query)

    context = {
        'project_list': project_list
    }
    return render(request, 'content/search_views.html', context)

和我的其他观点

def project_name_details(request, sid):

    majordetails = ProjectNameInviToBid.objects.get(id=sid)

    if request.method == 'POST':
        form = invitoBidForm(request.POST, request.FILES)
        form.fields['ProjectName'].initial = majordetails
        if form.is_valid():
            form.save()
            messages.success(request, 'File has been Uploaded')
    else:
        form = invitoBidForm()

    args = {
        'majordetails': majordetails,
        'form': form

    }
    return render(request,'content/invitoBid/bacadmininvitoBid.html', args)

我的表格.py

class invitoBidForm(ModelForm):

    class Meta:

        model = InviToBid
        fields = ('ProjectName','NameOfFile', 'Contract_No', 'Bid_Opening',
                  'Pre_Bid_Conference', 'Non_Refundable_Bidder_Fee',
                  'Delivery_Period',
                  'Pdf_fileinvi',)

和我的models.py

class ProjectNameInviToBid(models.Model):
    ProjectName = models.CharField(max_length=255, verbose_name='Project Name', null=True)
    DateCreated = models.DateField(auto_now=True)

    def __str__(self):
        return self.ProjectName


class InviToBid(models.Model):
    today = date.today()
    ProjectName = models.ForeignKey('ProjectNameInviToBid', on_delete=models.CASCADE)
    NameOfFile = models.CharField(max_length=255, verbose_name='Name of File')
    Contract_No = models.IntegerField(verbose_name='Contract No')

    def __str__(self):
        return self.NameOfFile

解决方案

首先，我要赞扬你的文件。大多数人未能提供重要的代码。

您可以在此处将类似的内容添加到您的代码中，这将满足您的要求。

我自己的代码中的一个例子

    if request.method == 'GET' and request.user.is_authenticated:
        study = Study.objects.get(pk=studyID)
        form = ContactForm(initial={'from_email': request.user.email, 'subject': "Study: " + study.name ,'message': study_message.format(request.user.get_short_name(), request.user.get_full_name())})

你应该如何改变你的代码

other views从此更改您的代码：

else:
        form = invitoBidForm()

至

else:
        form = invitoBidForm(initial={'ProjectName': <wherever your project name comes from>})
