Enable Multiple Buttons in a Form in Rails

Sometimes we need more than one button in the form. To do so in Ruby On Rails, we have to do the following:

Create a method in the controller to accept the form input

e.g

def approve_form

case params[:submit]

when "Approve"

redirect_to :action=>"approve"

return

when "Reject"

redirect_to :action=>"reject"

return

end

end

in your form, do this

If you encounter problems that the popup does not appear in link_to function in IE browser, below will solve your problem.

Make sure there is no space between the names of the window

window_name should not have spaces.

Cannot install rails. Set that proxy.

If you are installing gems or rails over a proxy, you may encounter the following problems.

Remember to set your proxy first as below:

In Windows:
gem install rails
ERROR: http://gems.rubyforge.org/ does not appear to be a repository

Before we begin, if you are behind a proxy, open the command prompt and give the following command:

 >Set HTTP_PROXY=http://:

For example, if the address of the proxy server is 192.168.1.1 and the port number is 9090, then you would have to give the following at the command prompt:

 >set HTTP_PROXY=http://192.168.1.1:9090 

Next, give the following command at the prompt:

 >gem update

Cannot Remove WD SmartWare. Disable It.

Here’s another way to keep the virtual CD volume from mounting (tested on Leopard):

1. Connect the new WD My Passport or other drive “infected” with this firmware

2. Open a Terminal and type something like:

diskutil info “/Volumes/WD SmartWare”

(this corresponds to the volume you want to get rid of)

3. Copy the large string of numbers that corresponds to “Volume UUID:” in the info.

4. Edit /etc/fstab as root using vifs:

EDITOR=nano sudo vifs

(if you want your usual editor, drop the “EDITOR=nano” part)

5. Add a line like the following, putting your UUID in from step 3:

UUID=that_big_number_from_step_3 none hfs ro,noauto 0 0

6. Save the file to quit out of vifs

7. Disconnect the My Passport and attempt to plug it back in and watch!

It’s a bit more involved than DSW, but you only have to do it once and the virtual CD volume won’t remount. WD really need to issue a firmware update that removes this virtual drive. At least give some of us the option of not having it!
