We are using the grails asynchronous mail plugin in our project and noticed that the sent mails never gets deleted from the database. This was an issue because we were sending out a lot of mails and all of them had PDF attachments of about 500 KB to 1 MB each. A sure recipe for disaster because our DB was growing exponentially. To take...
Our project went into production a few weeks back and was on Grails 1.3.1. Since the code was stable, we decided that it was time to upgrade to grails 1.3.4. However, we didn't want to push it straight to the QA Server or Production server because that would've meant that the maintenance of the existing production code would become a...
We have been using GitHub for version control in one of our projects and I am absolutely loving it! There are quite many advantages over a concurrent version control system like subversion. One of the commands I found useful was the stash command. It is of use when we are working on a piece of functionality, which is not in a state to...
In one of our projects, we needed to include QR Code on the PDF documents, which were to be sent out to the user and the printed version was to be received back from them. Once the documents were received, we were going to scan each sheet into an image file and then, these files were going to be read by the grails application, identify...
A scenario arose in one of our projects that we had to share some information between the grails application (which was taking care of dynamic content) and wordpress (which was used to maintain the static pages about the application). The information was the logged in user's name so that we could display that on the header. After giving...
In one of our projects, we had to create PDF documents from HTML. The iText renderer was an excellent solution to do that. However, the tricky part was that the cover page had to be of portrait orientation and the rest of the document, of landscape orientation. After doing a fair share of searching on the web, I came across the...
In one of the projects, we had used Query Caching to improve the performance. However, it also meant that the updates/inserts into a table did not get reflected immediately, i.e. something like: DomainClass.findByPropertyName("propertyName", [cache: true]) returned the same list as it was, before the insertion/updation took place....
Sometimes it is required that multiple Grails projects, hosted on a different Grails version, run simultaneously. In this case, while fixing bugs, you are required to run the application after switching the Grails version each time. To handle this scenario, I wrote a utility shell script "runGrails" to use a particular version of...
On one of our projects, we had to store the MySql Data at a location different from the default location. This was needed because the server was on an instance-store Amazon instance which meant that the data would get lost if the instance had to be rebooted for some reason. After going through the tutorials and articles on AWS, we came...
