Hi,

We already have a software, which is 90% finished. Now mostly we are doing bug fixes and adding new features.

If i want to start using CI, i need to start from step 1 ? That is rewrite all my existing codes ?

Is there anyway i can migrate my code to CI part by part. Rewriting all the part of the code to CI is lot of work, but if i can use CI in my existing project and add new codes in “CI WAY” it will be great.

Thanks,

Yujin

1) you could let your application as it is and “dive” into CI with this: http://ellislab.com/forums/viewthread/49423/ - I don´t know if its working properly, I never used it…

2) I you want integrate your application into CI step by step, I would first see, if it runs, if you include it in a controller/function… then, if your application is organized in files like main.php, this.php, that.php… would make at first a controller with functions like main(), this(), that() and simply include your scripts at first… if it runs you can use the recources of CI with $CI =& get_instance();...

then, whenever you have time, you can put your html part by part into CI view files, rewrite the db stuff, and so on…
I hope I helped a little bit, I have only experience with codeigniting small all-in-one-file scripts…

My suggestion :

Finish this application without CI.
And after that if u have time try to build it with CI
This is best test to compare it (Both method )  and good start to learn CI

Hi,

If your project is finished 90% , then you do not need to convert the things for only 10%.
First complete the 10% work and the last 10% is always crucial . After finish the project then you change the things in CI. And you will done it much faster in CI .

It depends a lot on how the application has been coded.  If the existing code makes use of get parameters, or mixes data access, html and logic together in the same file then it will take quite a bit of work to migrate to CI.  On the other hand, if it’s already written using a MVC style where presentation and logic are cleanly seperated it might be able to do it with only minor code refactoring.

Personally, if this is a commercial project, I probably wouldn’t bother trying to migrate the existing code.  Either just finish the app in the way you’ve been working, or build out the remaining 10% in CI and run it alongside the existing code.  If it’s a personal project where time is less of an issue that changes the equasion a bit.
