将变量从视图传递到表单

Question

@app.route('/product/<unique_form>',  methods=['GET', 'POST'])
def product(unique_form):
    form = ProductForm(**product_data)

class ProductForm(Form):
  #form

   def __init__(self, *args, **kwargs):
       #Here in the __init__ I need to access the unique_form value
       Form.__init__(self, *args, **kwargs)

我知道我可以为此使用会话，但可能有一种方法可以将变量从视图传递到表单 class。

像这样：

form = ProductForm(unique_form, **product_data)

这可能吗？

Answer 1

像这样：

@app.route('/product/<unique_form>',  methods=['GET', 'POST'])
def product(unique_form):
    form = ProductForm(unique_form, **product_data)

class ProductForm(Form):
   def __init__(self, unique_form, *args, **kwargs):
       # well, now you have unique_form here
       Form.__init__(self, *args, **kwargs)
