Mysql Dump in XML format

To take dump in XML format you have to provide an extra option in default mysqldump command. This can be useful in cases where you want to migrate your MySQL database to some other database.

You can use below command to take MySQL Database dump in XML format.

mysqldump --xml -u[username] -p[password] [db_name] > filename.xml


mysqldump -X -u[username] -p[password] [db_name] > filename.xml

For example if you have a database test_database with an username as root and password as mypassword the command to take dump will be,

mysqldump --xml -u root -p mypassword test_database > filename.xml

Handling two Django models in a single POST

There are times when, you want to handle multiple Django models in a single POST request (By this i meant data posted from html form/ template contains data of two different Django models). I was struggling with this few months back and got a fantastic reference link from #django on IRC.

You can use the below method as a simple example, here’s a view that updates a User and their Profile in one view:

def user_edit(request):
    if request.method == 'POST':
        user_form = UserForm(request.POST, instance=request.user)
        profile_form = ProfileForm(request.POST, instance=request.user.profile)

        if all([user_form.is_valid(), profile_form.is_valid()]):
            user =
            profile =
            return redirect(user)
        user_form = UserForm(instance=request.user)
        profile_form = ProfileForm(instance=request.user.profile)

    return render(request, 'user_form.html', {
            'user_form': user_form,
            'profile_form': profile_form,

The two most important things to notice here are:

a. The use of all() instead of user_form.is_valid() and profile_form.is_valid().

This is because Python will skip the if clause if the first form is not valid, and so it won’t run validation on the second form. If some error is present in second from user will again get the error second time. using all() runs validation on all the submitted forms thus you get the errors at one time.

b. Two forms in the context.

Just render them all inside the one <form> tag, and it will be fine. If any of the field names clash, pass a prefix= when constructing one of the forms, to prefix its field names so they’re unique.

You can check it by going to .ssh folder of home directory. If not please execute the below command and follow the instructions:

Step 1:

 ssh-keygen -t rsa 

After you are done with generating SSH key Please execute the below two commands on terminal.

 eval "$(ssh-agent -s)" 
 ssh-add ~/.ssh/id_rsa

git remote -v

Below result should be shown on Terminal.

origin (fetch)
origin (push)

Your fetch and push origin URL Will be listed. If it is a HTTPS URL change it by running,

git remote set-url origin

Verify it by running “git remote -v” again. You will get below result on terminal.

origin (fetch)
origin (push)

Now , goto your projects home and try to run git commands to Fetch/ Pull from origin it’ll work through SSH.

Ignore file permission changes in git

If the permission of a file changes inside a git repository,  Git identifies that as a changed file even though you haven’t changed that file. For example if you change a file’s permission from 644 to 755, It will be shown as a modified file. If you don’t want this to be shown as a modified file.

Execute below command in your repository home.

git config core.fileMode false

and if you want to change it for all the git repository in your system.

git config --add --global core.filemode false
