Hi: I searched the forum before posting and could not find any help on how to position an image using image_tag (''image_name''). I have an image in a div, and I need to move it to the right. How do I this? I have this code: <div id="mainDivright"><%= image_tag (''name.gif''), :options => {:align=>"right" } %></div> I

i want to integrated link_to with image_tag before i did link_to with image_tag like this <%=link_to image_tag(image.filename

hi, i''ve been through the rails apis and searched through past rails discussion, but i haven''t managed to find a way of aligning images with the image_tag() method. ideally i''d like to write something like image_tag("image.gif", :align => ''absmiddle'') to position the image vertically in the middle of some text. thanks luke

Hi, Any idea why image_tag doesn''t work within an email template? I''m trying to generate the URL for an image and I''m getting the following error. undefined method `request'' for #<Mailer:0x6a719e0> I''ve been able to use link_to but no luck with image_tag. I''ve seen a similar post to this in the list but no one has posted a response.

image_tag(source, options = {}) Ok, when I want to use an image I added the following code: <%= image_tag "dsf.jpg" options = {[align="right", style="padding-right: 10px; padding-top: 5px;"]} %> However, this doesn''t seem to work, it doesn''t like how I have the "options" part setup. I''m sure there is something very easy

image_tag() has :size option, but only takes height/width parameters. i want to be able to scale down the image by 50% because all my images are different sizes so i cannot be specific as image_tag() wants me to be. is there another RoR method i could use. note: i don''t want to resize my original images, i just want to be able to display them %50 smaller. hope i make sense. btw, great

First time here, so I hope this isn''t a FAQ (although I did check *the* faq). I''m using mongrel_cluster with --prefix, and it is very slick. Thanks for that. But I had one problem. At one point in my little app, I have something like this: image_tag(url_for(:action => ''picture'', :id => 1), :size => "160x200") In this scenario,

Is there any way to disable image_tag''s automatic escaping of special html entities in it''s :alt tag? Example: >From the controller: @sale[''title''] = ''My Company Product&copy;'' In the view: <%= image_tag(''path/to/file.png'', :alt => @sale[''title'']) %> Output: <img alt="My Company

hi, all, I have a problem with image_tag, the url it generates keeps adding ???? at the tail. e.g. src="/images/gicon.jpg?1153577588??????????" src="/images/gicon.jpg?1153577588?????????????????" I''ve checked the source code of image_tag, and couldn''t find any solution. The ???? is appended to the "source" parameter before it goes to the real

I have noticed that the image_tag helper method now appends a request parameter to the generated src attribute. With Rails 1.0/actionpack-1.11.2 I had <img src="/images/rss.gif" /> Now (1.1/1.12.1) I get <img alt="Rss" border="0" src="/images/rss.gif?1142366545" /> Is there any use for that number? Where does it come from? This is very far

Le''s say that I have a table called people and the column middle_name is nullable. If the user enters say blank or empty space then in the database it is recorded as empty space. I would like in all my models all empty spaces to be recorded as null. I guess I can write a plugin which will do so for all the models but I''m sure something like that should already be existing.I

In DHH''s keynote, he alluded to doing logins with REST. Has anyone implemented this, and if so, would you mind elaborating on how you did it please? Thanks in advance. -- Posted via http://www.ruby-forum.com/.

Hello All, How can I add a popup in link_to image_tag? I am trying as :- <%= link_to image_tag(@user.avatar.url(:small)), ''/users/edit'', :popup=>[''original_image'', ''height=700,width=900''] %> It goes to the edit page. But it doesn''t opens popup.
