Summarizing Summer

It was a great pleasure to work with great coders/developers at Plone Foundation and learning a lot from them during the course of the program. This blog is about summarizing the whole work I have done during this summer under Google summer of code 2016 under Plone Foundation. So my project mainly focuses on improving forms in plone for dexterity. We already have forms in plone for archetype. So there is a project named collective.easyform which basically provide forms for Plone as dexterity contenttype. The main focus of the project was to improve that code base. Make this stable for plone 5.0 and above. Make all the test cases passing for the code base. Try to cover tests as much as possible code base. Also implement functionalities for fields/actions of the forms in correct place. Make the plone more user friendly. Finally for users who want to migrate their already present forms in Plone Form Gen (PFG) which is archetype to easyforms which are dexterity based forms Plone. This w

Introduction to Code Base for easyform

So its been the end of community bonding period and I have been looking into the code base for which I will be working for this summer's project. Collective.easyform , A project for Plone which helps in create forms for plone using dexterity content type. So the project mainly focuses on Improving this add-on to work for properly for Plone5. Current Status of collective easyforms :- Wooh!! It's breaking and failing at lot of the parts. So right now the project is failing for tests and one of the main task of the project is the improve tests to make them work for project. Improving tests help us in tracking the future changes of the project so that we can see if new things/features are working properly in the code. Work done till now :- So till now I have done the setup for the project and did one feature correction, the basic mailer_template which is the default one is not able to render properly and it was showing error , so to make it fix everytime, we have to co

One Last Time

Okay. So finally the list of GSOC'16 selected students is out and I am glad that my project got selected under Plone Foundation. I am really looking forward to work on my project which is basically improving the add-on named easyforms. I have already started working on the same project and will plan with my mentor for future work. I will keep this blog updated with the work I will be doing during the project as I did last summer too. Cheers.

Tickling with tests

Hello everyone, So finally we have been at the end of the project and I really enjoyed each and every part of it. So after unit testing the transform its time to write functional tests and integration tests or we can say the browser tests for our add-on. I have written the functional tests to ensure that the new add-on is imported and all the profiles are installed and the editor is using our new transform and not the old transform. So for that we have already implemented the registration of new add-on to replace it with old one and we also have to make tinyMCE uses our new transform. How to make tinyMCE uses our new transform in place of old transfrom ? So for understanding that we should have the idea how tinyMCE calls for the transform script. So it uses getToolByName in portal_transform to get the required transform. So tinyMCE search for safe_html in portal_transform and the old transform was named safe_html. So here we had two ways to proceed :- 1) Either change tinyMCE

Testing the transform

Hello everyone, now the transform for filtering html is ready and the main task is to test the transform. For that purpose I have set up the whole test environment for my add-on using testing.py for unit tests and robot tests. After setting up the environment, now its time to first write unit test for transform that we have just created to check if they are all passing and the transform is working properly or not. For creating unit test I first created test class and in that class I just call the convert function that we have created in the transform and give the input as a data stream and pass it to convert function and then get the output as required. After writing few simple test cases like 30-35 then just ran these test cases and they ran successfully. Test cases ran successfully locally :- Travis is also happy ;) Yayayay!!! Finally test cases were passing so its like a milestone for the project and its completed. The PR got merged and things working good as expect

Updating the Transform

Hello everyone, its been quite a long time since I updated the post, So finally here is the recent work that I have done in past few weeks. As in the last blog post I was able to create a new transform script using lxml and I have mentioned the way I implemented that script. As the code have been reviewed, then Jamie (mentor) pointed me a very important bug that I have comparing regular expression with the strings and not with the tags which was a bug in that script, so what I did is that when I am converting the whole input of string into a tree form and then iterating through every node and then replacing or removing the unwanted tags as required. How to work with tree and replace tags ? So basically what I did is I just took the whole document as a string and parse it into HTMLParser which converts the whole string into a tree like structure. So here in this tree we will have a parent node and then the child nodes and we will iterate through the whole tree and manipulate the

The Transform Finally!!

Hello everyone, today I will tell you how I implemented the safe_html transform using lxml library of python. I tried to port the safe_html form CMFDefault dependencies to lxml libraries and tried to install my new transform in place of the old safe_html transform. So when ever our add-on is installed then it will uninstall the safe_html and install our new transoform. So there are a lot of things going on in the mind about lxml, why we use that and all.. So lets explore all these things. What is lxml ? The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt. It is unique in that it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API. Why we need to port the transform to lxml ? Earlier the safe_html transform had the dependencies of CMFDefault and we all are working to make plone free from CMFDefault dependencies as due to CMF
