Hi! If i have an object it''s easy. But i''m making a simple contact form and i check if email address is correct. If it''s not i redisplay the form with the info that there was an error (should i use redirect_to or render :action? what''s the difference?), but all previously submitted data is lost. I tried creating variables using names of the form fields, but it didn''t work. -- Posted via http://www.ruby-forum.c...

In a test app, I have a drop-down selection to change the language of the site. I use an Ajax request to an action in which the locale is changed, and the it''s redirected to the home page unfortunately, the locale seems to be changed but the home page doesn''t reflect the new language .. application_controller.rb .. before_filter :set_locale def set_locale I18n.locale =

I want to build a simple calculator with 1 form and a results page. The form will be redisplayed with an error message upon an invalid value entered. I won''t be using any database/active record for this. The problem i have is when i return to the form page i want to redisplay the values already entered in the form fields. Should i use text_field (which seems to be tied to a mode...

All, After a POST, I want to be able to redisplay a view with the data that was previously entered when my controller action notices a validation failure and calls render on the view that does the submit. Example: View x.rhtml - text field is filled in Call controller action Controller action fails validation calls render (:action => '&...

Hi all, is there a way to override the validation methods so as to avoid the div.fieldWithErrors divs from being created on the redisplayed form? Many thanks in advance, Nicky

I have a partial, it''s a shopping cart display, it''s designed to appear on several different pages of my site. One of the buttons on the shopping cart empties the cart, and then I want the calling page to redisplay. In other words, the cart controller needs to return the visitor to the same page -- however since the cart could appear on any given page, this has to be dynamic, not hard-coded. So the solution I''m considering is to use params[:controller], params[:action], and params[:id] as a uniq...

Hi, I''m confused about how form verification with AJAX works. Let''s say I have a ''new.rhtml'' view that contains a form with two fields, and the form action is ''create''. Let''s assume that I also want to do some type of data validation on one of the two fields via AJAX before I submit the form. But since I''ve already

I have a form. Everything submits into the database if I don''t have any validation rules. When I put these rules: validates_uniqueness_of :title, :message => "already exists in database" validates_presence_of :title I get this error (which seems weird because I am not validating against that): You have a nil object when you didn''t expect it! You

...d @staff_member.save flash[:notice] = ''StaffMember was successfully created.'' redirect_to :action => ''list'' else render :action => ''new'' end end However, if either of the models returns an error, the form gets redisplayed with the errors (all well and good), but the successful object is still saved. EG. If I don''t provide a staff_member e-mail address (required), then the app still goes ahead and saves the user info anyway. How do I stop it saving the other model if one fails. I thought about an if sta...

...have a two column page with the list on the left and the right side is reserved for the create/edit actions. On a successful save my rjs executes and updates the list view on the left and returns the right side to a "home" page. However, if one of the model validations fail I use rjs ro redisplay the edit action on the left, which I''ve had to make a partial for the rjs. The problem is that the standard form error messages don''t show up. I think they make be getting lost with the rjs since it''s not a redirect back to the edit action. Any ideas on how to solve t...

Is there a way to keep a controller instance variable across a link_to_remote call? In essence, I want the call to re-render a partial within my page with different display parameters, but without doing another DB call. Is there a simple way to do this?

...0 The file dskdiag.0 if a copy of pxelinux.0 that I hex edited changing default to dskdiag. When I run this setup default menu is displayed and I can choose the submenu (dskdiag). The submenu is then displayed, but when I choose "M" to go back to the top menu the submenu (dskdiag) is redisplayed. Any one have any thoughts on what is going wrong?

...orking on an file upload page that uses an ajax progress bar (http://sean.treadway.info/demo/upload/). I''ve also got validation on the uploads (must be a certain file size/mime type etc). When uploads pass validation - all is dandy. But when they fail - I can''t work out how to redisplay the form with the flash error messages (that normally appear when not using the ajax progress bar). I''m new to RoR so apologies if i''ve missed something simple. I guess this has to do with the form being submitted to a hidden iframe? So how can I display the error messages to...

Hi again... One more item.. the file_column plugin uses a tmp directory inside the /public directory to store a temporary uploaded item. But it looks like this folder is just going to grow and grow. Is there some way to clear this out or not cause this to happen? Thanks once again! -- Posted via http://www.ruby-forum.com/.

Hi all I wanted to ask why Rails'' password_field helper uses the input password as default value when reloading a form because of errors? Isn''t this a potential security leak? On any other webs I''ve seen so far the password fields have to be filled in again after every reload of the site so the password doesn''t exist in plain text in the html code... What

...le Rails development book again and thought to see what effect, if any, placing a doctype declaration at the top of an rhtml file would have. When I insert any of the three standard forms of such declaration at the top of app/views/store.rhtml the product image disappears when the web page is redisplayed.

I am trying to write some simple code post a form, update the database and do some validation. I have 2 problems: 1) The validation fails but I can''t get hold of the error message 2) I can''t get the form to redisplay the previously entered data for the user to correct. I have 2 controllers: user and holiday. A user can request a new holiday by filling in a form. I have a request_holiday method in the user controller. My request_holiday.rhtml sets up a form as follows: <%= start_form_tag :controller...

Hi people. I need your help here, please. I have a rails 3.0.9 app, and I''m using Ajax to save some records to the database. To achieve this, I use a jquery modal form, but one of the fields is a datepicker, and if I click on it to display the calendar it doesn''t work. The thing is, I press submit without fill all the fields, so, my custom validations were shown, telling me

In an early section on Action View, showing code being put directly into the rhtml file: <% require ''date'' DAY_NAMES = %w{ Sunday Monday Tuesday Wednesday Thursday Friday Saturday } today = Date.today %> <h1>Hello, Dave</h1> <p> It''s <%= DAY_NAMES[today.wday] %>.
