Django：多くのフォームを1つのテーブルに格納

Question

私はdjango v1.8を使用しています。

Aテーブルを4つのフォームに分割します。私views.py

ext_cent = ExternalCentersForm(request.POST, prefix='extcent') 
ext_cent_diagnostic = ExternalCentersDiagnosticForm(request.POST,prefix='extcentDiagn') 
ext_cent_outcomes = ExternalCentersOutcomesForm(request.POST,prefix='extcentOutcomes') 
ext_cent_outcomes2 = ExternalCentersOutcomes2Form(request.POST,prefix='extcentOutcomesTwo') 

から

例私はそれらを保存しようとしている私は

ext_cent_object = ext_cent.save(commit=False) 
ext_cent_object.author = request.user 
ext_cent_object.save() 
ext_cent_diagnostic_object = ext_cent_diagnostic.save(commit=False) 
ext_cent_diagnostic_object.author = request.user 
ext_cent_diagnostic_object.save() 
ext_cent_outcomes_object = ext_cent_outcomes.save(commit=False) 
ext_cent_outcomes_object.author = request.user 
ext_cent_outcomes_object.save() 
ext_cent_outcomes2_object = ext_cent_outcomes2.save(commit=False) 
ext_cent_outcomes2_object.author = request.user 
ext_cent_outcomes2_object.save() 

マイforms.pyを使用します。models.py

例

各フォームの結果として、特定のフォームの値のみを含むテーブルに新しい行があります。これらのフォームのすべてのデータを1つのテーブルに格納する必要があります。あなたを保存する代わりに

Answer 1

は、ここで「更新」

を必要とする例である：

ext_cent_stored = Ext_centers.objects.get(center_id=ext_cent_object.center_id) 

    form = ExternalCentersForm(request.POST, instance=ext_cent_stored) 
       if form.is_valid(): 
        form.save() 

    form = ExternalCentersDiagnosticForm(request.POST, prefix='extcentDiagn',instance=ext_cent_stored) 
       if form.is_valid(): 
        form.save() 

    form = ExternalCentersOutcomesForm(request.POST,prefix='extcentOutcomes', instance=ext_cent_stored) 
       if form.is_valid(): 
        form.save() 

    form = ExternalCentersOutcomes2Form(request.POST,prefix='extcentOutcomesTwo', instance=ext_cent_stored) 
       if form.is_valid(): 
        form.save() 

すべての保存方法について使用これを、あなたは、古いデータを失うことはありません。

ありがとうございました。
