django forms error_class -

-

Is there a way to provide a specific error in the function in fire defragment? Under the docs, it shows that you can give a form a special error rendering function, but it seems like you have to declare when you have the form, not when you have an illustration of defining it.

You can define something like ErrorList class: 

  Import ErrorList class DivErrorList (ErrorList) from django.forms.util: def __unicode __ (self): Return self.as_divs () DEF as_divs (self): Otherwise self: return you 'U' return U '& lt; Div class = "errorlist" & gt;% s & lt; / Div> % '' .join ([U '
< P> And then when you have an explanation of your form, you can illustrate this with error_class: 

  f = ContactForm (data, auto_id = false, error_class = DivErrorList) f.as_p ( ) & Lt; Div class = "errorlist" & gt; & Lt; Div class = "error" & gt; This field is required. & Lt; / Div & gt; & Lt; / Div & gt; & Lt; P & gt; Subject: & lt; Input type = "text" name = "topic" maximum length = "100" /> < / P & gt; & Lt; P & gt; Message: & lt; Input type = "text" name = "message" value = "hello there" /> & lt; / P & gt; & Lt; Div class = "errorlist" & gt; & Lt; Div class = "error" & gt; Enter a valid e-mail address. & Lt; / Div & gt; & Lt; / Div & gt; & Lt; P & gt; From: & lt; Input type = "text" name = "sender" value = "invalid e-mail address" /> gt; & Lt; / P & gt; & Lt; P & gt; CC itself: & lt; Input checked = "checked" type = "checkbox" name = "cc_myself" /> gt; & Lt; / P & gt;

But every time I use a form, I do not want to name the error class, is there a way to define a custom error renderer within the form definition?

If you want this behavior to be normal in all your forms, then you have your own form base Class can be defined like: 

  class MyBaseForm (forms.Form): def __init __ (auto, * args, ** kwargs): kwargs_new = {'error_class': DivErrorList} kwargs_new .update (kwargs) super (MyBaseForm, self) .__ init __ (self, * args, kwargs_new)

And then one that is all your subcategory form. Then all of your form will have DivErrorList as a default error renderer, and you will still be able to change it using the error_class argument.

For ModelForm: 

  class MyBaseModelForm (forms.ModelForm): def __init __ (auto, * args, ** kwargs): kwargs_new = {'error_class': DivErrorList} kwargs_new.update (kwargs) super (MyBaseModelForm, itself) .__ init __ (* args, ** kwargs_new)

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
