It seemed that the javascript was not firing for some reason.

I had the jquery-rails gem in my Gemfile ok but jquery was not being loaded.

Eventually I worked out a solution (there may be better solutions…)

In my application.html.erb layout file my javascript include was :

<%= javascript_include_tag :defaults %>

which meant that I was trying to load a defaults.js file which didn’t exist.

I changed this to

<%= javascript_include_tag :application %>

and suddenly everything is working, i.e. application.js is being loaded and destroy links are now doing what one would expect.

Simples.

I haven’t worked with merb before so there was something of a learning curve, but not too much.

Anyway, the site uses image science for image manipulation.

Once I had everything installed , trying to run merb in the application root gave me the following error:

/usr/bin/ld: cannot find -lstdc++

From the trace this seemed to be related to ruby inline.

Anyway, short version is that once I installed libstdc++6-4.4-dev merb was able to start up ok.

I hope this helps someone else out there.

As they were restricted to one IP address I went down the wildcard ssl route.

There is a lot of conflicting information out there about how to go about installing a wildcard ssl certificate in cpanel. Some sources say it’s not possible. Others say it is but you have to edit lots of cpanel config files by hand (which is never a nice thing to have to do).

In the end it was relatively straight forward.

I generated a key and csr by hand on the server by the usual methods. i.e. openssl genrsa etc etc.

The key here was specifying the domain as *.domain.com .

I then bought the wildcard ssl certificate.

Finally, I logged in to the client’s cpanel account, went in to the ssl/tls manage but, and then the Activate SSL on your website part.

I selected domain.com from the dropdown, pasted the contents of the crt file and the key I generated earlier, and clicked the Install Certificate.

And much to my surprise it worked.

ymmv, ianal, bbqrofl

The command to install this specific version of gem is

gem update –system 1.6.2

uninitialized constant Rake::DSL

It would seem that this error is related to the version of rake installed on the server.

I installed an older version and removed the latest version.

gem install rake –version=0.8.7

gem uninstall rake –version=0.9.2

Everything is working ok now.

Hint found here.

So something like:

var return_string;
return_string += "Some stuff";

Wrong!

var return_string = "";
return_string += "Some stuff";

Right!

Obvious really…

$("#<%=import.id%>").poll({
    url: "/mis_imports/import_state/<%=import.id%>",
    interval: 3000,
    type: "GET",
    success: function(data){
                   var return_data = eval('(' + data + ')');
                   $("#<%=import.id%>").attr("class","mis_import_state_"+return_data.state);
		   $("#<%=import.id%>_message").html(""+return_data.status+"");
		   $("#<%=import.id%>_timestamp").html(""+return_data.timestamp+"");
		   if (return_data.state == 1){
		     $(this).stop();
		   }
    }
});

And on the server, my rails action method looks like this:

def import_state
    import = MisImport.find(params[:id])
    render :text => {:state => import.state,:status => import.message,:timestamp => Time.now.strftime("%d:%b:%Y %H:%M:%S")}.to_json
  end

The key part to this working is line 6 of the javascript listing, where one ‘evals’ the data returned from the server.
This effectively rehydrates the data structure into a usable javascript object, and that’s the bit I keep forgetting!

There are probably smarter ways of doing this; I know there is a jQuery.getJSON() function, but in this case I couldn’t work out how to use that with jquery poll. Again, probably very simple…

The code I had in my class file looked something like this:

public function preInsert(Doctrine_Event $event)
{
$this->calculate_status();
}

This seemed correct, but I was getting this strict error.
Anyway, short story shorter, I removed the Doctrine_Event (type hint?) from my method signature and the warning went away.
New code looks like this:

public function preInsert($event)
{
$this->calculate_status();
}

Anyway, one of the problems I’ve had a few times over the current project is the error
“couldn’t get last insert identifier”

So far, the problem has been down to the object I have been trying to create didn’t have it’s id field set to autoincrement. Or perhaps more accurately, setting that model’s id field to autoincrement has sorted the problem so far.
Hopefully once I get the hang of the schema file and the (what appears to be) the slightly different syntax for migrations, all my models should have autoincrement id fields and this shouldn’t be a problem anymore.
