I currently have allowed admins to delete a user by having
link_to("Delete", admin_path(resource), :confirm => "Do you want to delete this item?", :method => :delete)
How do I add the option for view, where I want someone to view that item?
Rails applications typically respond to various actions based on HTTP verb, which routes to a method for that Controller. The comments point out the correct code to link to the default show method for the Controller:
link_to("View", resource_path(resource))
However, you have to actually have a method written to retrieve and display the contents of the resource, including a template to display the fields, etc.

I need to call a method on Button click from my view. Below is the code in my view:
<button type="submit" id="1"><%link_to "Done", {:controller => :summary, :action => :done_order}, {:method => :put }%></button>
On click of this button, I have to delete a row from table and update the view with updated contents. Below is the done_order method in my controller
def done_order
List.where(:tableno => #orders.first.tableno).delete_all
redirect_to :action => :index
end
When I click on button I need to delete all rows(for a particular table number) from 'lists' table and redirect to index, which will again fetch rows from lists table in #orders and pass it to view to populate.
In routes file I have defined as: put "summary/done_order"
Problem is its not performing anything on click. I have tried numerous suggested ways with button_to & link_to but everytime landing up with some error. If there's no error then nothing is being performed.
I believe there is some shortcoming in my understanding to implement this and I am missing something on trying alternate ways. Please advise. thanks.
You should setup a route for this:
# routes
resources summaries do
put :done_order, on: :member
end
This should allow to write something like this:
= link_to "Done", done_order_summaries_path(#summary), method: :put
I'm not sure what you've named your objects, but it doesn't seem you've followed convention. So that part is up to you, but that's the basic mechanism. Another note is that you've put a link inside a button tag. I'm not sure that's even valid. There's no need for you to do that. Just style your link to look like a button or use a button instead, or even a button with a form.
How can I pass and collect different options into a controller action.
E.g you have a Team model and you want to add or remove Users from the team?
I would assume this would go in the update action of the teams controller, but the update action also need to be able to update team details like name, address, ect.
I tried the following code but that produce some weird results to my css and produces errors.
link_to team_path(user), params[:add] ,:class => 'btn btn-mini pull-right', :method => :put
Weird results are probably caused by the mixed parentheses
params[:add}
what does your model look like? (Teams-Teammember relation?)
But in general:
- you should add actions to the appropriate controller (prob. teams_controller) for
adding and deleting members:
def add_member
end
def remove_member
end
and define routes in config/routes.rb to be able to use this actions (there are plenty of examples how that can be achieved in the comments generated), then you can use the resulting path helper for your link_to tag - check out the available routes and path helpers with
rake routes
My articles can appear on several sites, so as well as an article model with title, body etc and a site model with site_id, site_name etc, I have I have an article_site_permission model, with article_id, site_id and visible which can be either true or false.
On my article edit page, I've done a button_to:
<%= button_to 'Hide', article_site_permission_path(:id => #article_site_permission_id, :article_site_permission => {:visible => "false"}), :method => :put %>
This works - it changes the permission to false. And I can show the Show button which does the reverse.
Now I want to refresh the div that has the button in it by adding :remote => true to the button link. But where do I put my javascript?
Is it in the article_site_permission view - even though I'm looking at a view of the article itself?
Is it called update.js.erb?
Thanks for your help.
Update for clarity.
My button is on the articles/edit page. The button updates article_site_permissions. I want to go back to articles/edit and refresh the div that has the button in it.
I must edit the update controller for article_site_permissions, but where do I put the js to refresh the div?
In your controller, redirect to the action you want (index, show, etc.). Do a
respond_to do |format|
format.js
end
under that action in your controller. Then, in the corresponding view, have a file named
index.js.erb
Or replace index with whatever action, just be sure to give it the same name as the action that's calling it.
EDIT
I should also mention you are correct in adding the remote true to your button. It's hard to tell from your question what action you're trying to reach in which controller. If you're trying to access the show action of the ArticleSitePermission controller, you're doing well. However, it seems like you're not trying to route to show. Check out this link for more info on routing to different actions.
EDIT 2
This should do it.
<%= link_to 'Click me', {:controller => "article", :action => "update", :id => #article_site_permission_id },
:remote => true %>
Also, if all you want to do is redirect to the article, you don't need to do js. Just redirect to articles#show
I'm trying to build a CMS in Rails from scratch, and for showing the user generated pages I'm having trouble deciding exactly how to do it.
The way I have it right now, I have a controller named 'content' with a single action called 'show'. In routes.rb I have a rule that passes any name after the name of the website to the content controller, show action with parameter name.
For example, www.mysite.com/about_us would route to
:controller => 'content', :action => 'show', :page => 'about_us'
Inside the content controller, I do a find on the Pages model to locate the named page:
#markup = Page.find_by_name(params[:page])
And then in the show.html.erb view I use the raw helper to display the content:
<%= raw #markup.text %>
Does this method violate anything about the way I should do be doing things in Rails? Or is this an OK solution?
I ended up using the sanitize helper, by default it removes <script> tags which is essentially what you need to prevent XSS, as far as I understand. For those who have found this via a search, the only code that changes from what I described above is that in the view you change to:
<%= sanitize #markup.text %>
I'm creating in my index page of my ruby on rails program, a list of the most commonly searched for terms in my database and hence each time a user selects a specific category this is written to another database.
What i would like it to create a hyperlink and pass a certain amount of parameters to a form like is usually done with a select_tag but instead with just a hyperlink, i would like to pass a set of hidden fields that i have on the page as well as what the user has selected.
To give you a better idea, basically i have the following structure in my program:
User inputs a search on (index.html.erb), user clicks on submit tag
action, user is taken to search.html.erb page and is displayed a set of refined categories + some fields, submit button,
user is taken to closest.html.erb (which uses parameters from the previous form by invoking the params[:searchSelected] and a few other params. )
I would also like to add this functionality:
Mimick this same operation, but instead of going in the search.html.erb, i would click on an already refined search category on the index.html.erb page (from a link_to , transmit as parameters which link_to the user has chosen + the hidden fields.
i Currently have this code
#stats.each do
|scr|%>
<%= link_to scr.category, :action => 'closest', :id => scr.category%>
I'm not sure if this is relevant, but i currently have the following routes in my routes.rb file
map.resources :stores, :collection => { :search => :get }
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'
would anyone please assist me please? this is my first ruby on rails project and i would really like to find a way around this please
I am not sure if this is what you were thinking, but you can add additional parameters to the link_to tag. They are then available in your controller. So:
<%= link_to scr.category, :action => 'closest', :id => scr.category, :other_param => "test" %>
Will be available in your controller.
def closest
params[:other_param] == "test" #this will be true
end
i managed to resolve this by taking the params[:id] and then according to the value either set my own values (instead of the hidden ones in the index.erb which i had set manually anyway) and otherwise, continue as usual had i placed a regular search
View:
<%= link_to obj.ptc_devicename ,"/wiuconfig/hd?idval=#{obj.id.to_s}&val=#{#devicetype}",:value => obj.ptc_devicename,:id =>obj.id %><br/>
Controller:
#Heading= params[:val]
#id=params[:id]
value will be id is 2 and val is #devicetype
