Hello,

I accidentally posted this to the “Ruby” forum when it should have gone  
here – sorry.

I am using \*\_path in views and \*\_url in controllers (with redirect\_to,  
for example). It is my understanding that this is generally considered  
a good practice.

I want to use my app using https, and thought it would work that way as  
long as I loaded the app by browsing to [https://my.app.com](https://my.app.com). However, it  
appears that even if I do this, redirect\_to some\_model\_url generates a  
url with a protocol of https://.

How do I get \*\_url to generate a url with https:// for the protocol?

Regards,  
Errol

I assume you meant to say “http://” ?

some\_model\_url(:scheme =\> ‘https’)

Yes! I thought I proof-read so well…

Thanks for the response. I guess I was looking for a way to do this  
application-wide. It would not be very DRY to have to add (:scheme =\>  
‘https’) to every place in my app where I call a \*\_url helper.

Is there another way?

Besides, using relative paths in redirects violates the HTTP spec. I  
understand that it gets the job done, but that doesn’t seem like the  
right way to do it.

I don’t wish to appear argumentative, but I really hope somebody knows a  
cleaner way to do this.

Use \*\_path? I do it and haven’t seen any browsers complain about the  
redirects…

Use default\_url\_options.

Hi Errol,

If you want to pull out data in csv format from an existing mysql  
database using Rails, this is the easiest way to do it :

1. install fastercsv : sudo gem install fastercsv
2. Add on top of your controller : require ‘fastercsv’
3. Create an action in your controller and its corresponding view

# The action

def import\_csv  
result = YourModel.find(:all, :conditions =\> “your\_condition”)  
@outfile = “your\_csv\_report\_name\_” + Time.now.strftime("%m-%d-%Y") +  
“.csv”  
csv\_data = FasterCSV.generate do |csv|  
#field names  
csv \<\< [“Field\_name\_1”]  
csv \<\< [“Field\_name\_2”]  
#Data  
result.each do |table|  
csv \<\< [table.field1 table.field2]  
end  
#Write data in csv format  
send\_data csv\_data,  
:type =\> ‘text/csv; charset=iso-8859-1; header=present’,  
:disposition =\> “attachment; filename=#{@outfile}”

```
redirect_to :action => "your_action"

```

end  
end

#The view  
\<% form\_tag :action =\> “import\_csv” do %\>  
\<%= submit\_tag ‘Import CSV’ %\>  
\<% end %\>

Hope this helps!
