Fixing a mistake after commiting in Git

So, I ran into an interesting issue while coding today. I made a lot of changes and committed code to my Git repository. Just after committing, I realized that I still had to make some changes to a file and those changes should also have gone in with the previous commit.

Fixing a commit mistake can be done in two ways. Revert the commit, make the changes and then recommit them. This is the preferred way if we have already made the changes public (and thus someone may already have pulled them). However, in my case I am the only one working on this project right now and I had not pushed the changes to GitHub, so I could try the other method.

So here's what I did. I made changes to the file, added it to the index, and committed it thus:

$git commit --amend


Committing code with the --amend switch will cause the index to be committed as part of the previous commit. Git also brings up the editor window, in case we want to change the commit message. This method can also be used to change the commit message without adding any files to the commit.

Hi parag,
Could you please share the template of your blog? It is really neat and cool. I would like to use the same template on my blog. I did customize the default template but I could not make it the exact way in which I wanted it to be.

Inheritance vs. composition depending on how much is same and how much differs

I am reading the excellent Django book right now. In the 4th chapter on Django templates , there is an example of includes and inheritance in Django templates. Without going into details about Django templates, the include is very similar to composition where we can include the text of another template for evaluation. Inheritance in Django templates works in a way similar to object inheritance. Django templates can specify certain blocks which can be redefined in subtemplates. The subtemplates use the rest of the parent template as is. Now we have all learned that inheritance is used when we have a is-a relationship between classes, and composition is used when we have a contains-a relationship. This is absolutely right, but while reading about Django templates, I just realized another pattern in these relationships. This is really simple and perhaps many of you may have already have had this insight... We use inheritance when we want to allow reuse of the bulk of one object in other ...

Testing Groovy domain classes

If you are trying to test Grails domain class constraints by putting your unit test cases in the 'test/unit' directory, then your tests will fail because the domain objects will not have the 'valdate' method. This can be resolved in two ways: Place the test cases inside test/integration (which will slow things down) Use the method 'mockForConstraintsTests(Trail)' to create mock method in your domain class and continue writing your test cases in 'test/unit' What follows is some example code around this finding. I am working on a Groovy on Grails project for a website to help programmers keep up and refresh their skills. I started with some domain classes and then moved on to write some unit tests. When we create a Grails project using grails create-app , it creates several directories, one of which is a directory called 'test' for holding unit tests. This directory contains two directories, 'unit', and 'integration' for unit and ...

Running your own one person company

Recently there was a post on PuneTech on mom's re-entering the IT work force after a break. Two of the biggest concerns mentioned were : Coping with vast advances (changes) in the IT landscape Balancing work and family responsibilities Since I have been running a one person company for a good amount of time, I suggested that as an option. In this post I will discuss various aspects of running a one person company. Advantages: You have full control of your time. You can choose to spend as much or as little time as you would like. There is also a good chance that you will be able to decide when you want to spend that time. You get to work on something that you enjoy doing. Tremendous work satisfaction. You have the option of working from home. Disadvantages: It can take a little while for the work to get set, so you may not be able to see revenues for some time. It takes a huge amount of discipline to work without a boss, and without deadlines. You will not get the benefits (insuranc...
