如何将Django表单转换为dict,哪些键是模板中的字段ID,值是初始值? [英] How to cast Django form to dict where keys are field id in template and values are initial values?
问题描述
这样的东西:
{'field1_id_in_template':value1,...}
有人知道怎么做吗?
我可以添加前缀'id_ '对于form.fields字典中的每个字段名称,但如果有人更改了widget.attrs的id,我可以有问题
答案: p>
这是CBV的方法:
def post_ajax(self,request, * args,** kwargs):
form = ChooseForm(request.POST,log = log)
如果form.is_valid():
instance = form.save()
inst_form = InstanceForm(instance = instance,account = request.user)
fields = {}
在inst_form.fields中的名称:
如果inst_form.initial中的名称:
fields [ inst_form.auto_id%name] = inst_form.initial [name]
return HttpResponse(
json.dumps({'status':'OK','fields':fields},
mimetype = appplication / json'
)
assert False
这就是为什么我这样做:
有了这个响应,我可以在客户端上写这样的东西。现在我不需要手动初始化页面上的所有字段
function mergeFields(data){
for var id in data){
$(#+ id).val(data [id])。change();
}
}
你可以尝试 getattr 。
例如,您有一个已知的密钥列表为
['field1_id_in_template','field2_id_in_template',...]
然后:
my_values = dict()
key_list中的键:
value = getattr your_form,key)
#现在用它做某事
my_values [key] = deal_with(value)
I have a huge django form and I need to create dict where keys are field id in template and values are initial values? Something like this:
{'field1_id_in_template': value1, ...}
Does somebody know how do that?
I can add prefix 'id_' for each field name in form.fields dictionary but I can have a problem if somebody change id for widget.attrs
Answer:
This is method of CBV:
def post_ajax(self, request, *args, **kwargs):
form = ChooseForm(request.POST, log=log)
if form.is_valid():
instance = form.save()
inst_form = InstanceForm(instance=instance, account=request.user)
fields = {}
for name in inst_form.fields:
if name in inst_form.initial:
fields[inst_form.auto_id % name] = inst_form.initial[name]
return HttpResponse(
json.dumps({'status': 'OK','fields':fields},
mimetype='appplication/json'
)
assert False
And this a reason why I do that: With this response I can write something like this on client. Now I don't need to manualy initialize all fields on the page
function mergeFields(data) {
for(var id in data) {
$("#"+id).val(data[id]).change();
}
}
you can try getattr.
For example, you have a known key list as
['field1_id_in_template', 'field2_id_in_template', ...]
Then:
my_values = dict()
for key in key_list:
value = getattr(your_form, key)
# now do something with it
my_values[key] = deal_with(value)
