下面描述的表单无效。表达式{{ search_id_form.errors }}
并没有显示任何内容。
Django模板:
<form method="POST">
{% csrf_token %}
{{ search_id_form.idtype.label_tag }}
{{ search_id_form.idtype }}
{{ search_id_form.index.label_tag }}
{{ search_id_form.index }}<br>
<input type="submit" name="id_search_button" value="Submit">
</form>
Python类:
class IDSearchForm(forms.Form):
idtype = forms.ChoiceField(
choices=[('idx', 'Our Database ID'), ('uprot', 'UniProt'), ('ncbi', 'NCBI')],
initial='idx',
widget=forms.RadioSelect,
label="Which identifier to use:"
)
index = forms.CharField(label="Identifier:")
查看:
def search(request):
if request.method == 'POST':
# handling other forms ...
# find a toxin by id
if 'id_search_button' in request.POST:
search_id_form = IDSearchForm()
if search_id_form.is_valid():
idtype = search_id_form.cleaned_data['idtype']
index = search_id_form.cleaned_data['index']
return render(request, 'ctxdb/result_ctx.html', {
# here I try to use predefined object to pass to renderer (for debugging)
'ctx': get_object_or_404(CTX, idx='21')
})
# handling other forms ...
# other forms
search_id_form = IDSearchForm()
# other forms
return render(request, 'ctxdb/search.html', {
# other forms
'search_id_form': search_id_form,
# other forms
})
在视图功能中,我在单页上处理四种不同的形式。其他形式正常工作。这有什么问题?

调用.is_valid
时,您需要将数据传递给您未执行的search_id_form
。
更改
search_id_form = IDSearchForm()
到
search_id_form = IDSearchForm(request.POST)
