There was no reply to this question but it must be a common requirement. Is there a good solution? How would one get a validates\_\*\*\* from the model to apply when using in\_place\_edit\_for? – Brian ---

The In\_place\_editor still uses the callbacks like before\_update, so maybe your could force your validation requirements to fire that way. – Timothy J. ---

I’ve just created a custom in\_place\_edit that validates the model and display the error message in javascript alert box.

Naga, I’m not sure what went wrong though, it’s a bit hard to know without looking at the codes. Use firebug, check out the Ajax request generated, put a print statement in your codes, look at the log files, you probably would be able to see something helpful. ---

Hi, Thanks a lot, its working fine , i am sorry that i have given the wrong column name for validates\_presence\_of in the model,its good, and every body liked that, and i would ask u one more thing, is there any alert box custom code for validating the Ajax form, like if i click a link an ajax form appears and if i give a blank and submit its not taking the value in the database but i should get an alert saying that it is blank, Thanks in Advance, Harish ---

Hey naga, I forgot to mention that you’ll need to restart your mongrel server. Did you do that? ---

Laurynas, Please add append the following lines to custom\_in\_place\_editing.rb, I updated the code snippet yesterday to fix caching issue on Rails 1.2, which causes the entry to be blank, after the error message alert. But I forgot to copy a few lines below. ActionController::Base.class\_eval do include ActionController::Macros::CustomInPlaceEditing end Harris, I’m not sure what you meant though, sorry. ---

Looks like a nice piece of code 😉 I’m rails newbie and have some problems integrating it. I’ve created custom\_in\_place\_editing.rb in my lib/ and added include to my environment.rb, but I’m still getting ‘uninitialized constant’ error if I add ‘in\_place\_edit\_with\_validation\_for’ to my controller. I did server restart. Do you have any idea? Thanks in advance, Laurynas On Mar 20, 8:05 am, Herryanto S. \ **Author:** ![jjkiesch](https://www.ruby-forum.com/letter_avatar_proxy/v4/letter/j/bc79bd/32.png) [@jjkiesch](https://www.ruby-forum.com/u/jjkiesch)\ **Post date:** [April 1, 2007, 1:23pm UTC](https://www.ruby-forum.com/t/validation-with-in-place-edit-for/56544/13 "2007-04-01T13:23:13Z") Maybe I replied too quickly 🙂 Now I noticed, that I’m getting “undefined method ‘query\_cache’” exception if validation fails. If I comment out “object.to\_s.camelize.constantize.query\_cache.clear\_query\_cache”, I get correct validator error message, but then blank value is shown. That’s on Rails 1.2.3.

Laurynas, I forgot that I’m using RailsOnEdge. You are right, there’s no query\_cache in rails 1.2.3. I’ve applied the patch to handle that. Please re-copied the source codes from the same place: [http://www.pluitsolutions.com/2007/03/20/custom-in\_place\_edit-with-validation/](http://www.pluitsolutions.com/2007/03/20/custom-in_place_edit-with-validation/) Sorry for the confusion, and thanks for reporting that. ---

Herryanto, after first test everything looks ok. Thanks again! Laurynas On Apr 1, 7:13 pm, Herryanto S. \
