problems with pulling or pushing the code - ruby-on-rails

My question is very basic but still it is unclear for me. I am working on a rails project with multiple developers. All of them can pull or push the project. So let me explain my scenario. If I am making changes in my code for the first time and the other developers are also making changes, when I try to push the project I am able to do so. But the other developer face problem in pulling the project. After that If they are able to make changes and pull the project then I am unable to push the project or pull the project. This is how we push the project first:
git add .
git commit .
git pull origin master
but the error comes warning: Cannot merge binary files or I get the error git pull fails with “Untracked working tree file 'blah' would be overwritten by merge

The problem is coming because you and your friend doing changes on the same line of the file and git is unable to decide which one to take. So in this case its better to go for stash first to save your code.
The code will be:-
git stash :- To save your code
git pull :- To pull the code from git
git stash apply :- To merge your changes with the pulled files, if any merging error is coming then it will hit an error saying merge-conflict,you have to resolve that manually.
git add :- To add the files
git commit -m "Commit message" :- To commit it
git push :- To push to the repo.
I think this will solve your problem

git checkout accepts --ours or --theirs options for cases like this. So if you have a merge conflict, and you know you just want the file from the branch you are merging in, you can do:
$ git checkout --theirs -- path/to/conflicted-file.txt
to use that version of the file. Likewise, if you know you want your version (not the one being merged in) you can use
$ git checkout --ours -- path/to/conflicted-file.txt

In your case the file is 'blah' in the working directory of remote location. so u can keep one of them.

How to fix Bitbucket warning "You appear to have cloned an empty repository"?

I am using the Bitbucket tool in my project, so I created the clone URL and I tried to add my local code into the repository. I am using Terminal for the cloning process. while the process I am getting the error like this "Warning: You appear to have cloned an empty repository.".
I want to clone my project and I have to upload my codes into the repository. if anyone knows how to fix this, could you please help me.
Once you have cloned your (empty) repository, you still need to:
add files in the local folder created by the git clone command.
type
:
git add .
git commit -m "First batch of files"
git push -u origin master
Then your remote BitBucket repository won't be empty anymore.
This happens when you are cloning a freshly created repository with no commits.
As it says, it is just a warning. If it is expected that there is nothing in the repository, you can go ahead and add files and commit and push back.
to push it
git add --all
git commit -m 'your commit message'
git push origin master
If it is not supposed to be empty, contact the person/admin who gave you the link.

How do I pull your last commit from GitHub to C9?

So, I kind of messed up and went and deleted all my files on C9. I haven't saved anything yet, so I'd like to pull my last commit into my C9. I read somethings that said I should download the zip file of the commit, but I don't really know what to do with that. If anyone could help me I would really appreciate it!
If you guys need any more info, I want to pull from my last commit because I deleted all my branches except my master branch and all the hidden files that I might need later. I couldn't really find anything about pulling into C9 from Github so I thought this would be a good question to ask you guys.
you can delete all the files that you do not need then run the following
cd ~/workspace # make sure you are in the right folder
git init . # create new git repo instead of the one you've deleted
# now add your github repository as origin
git remote add origin git#github.com:jinntakk/upskill_saas_tutorial.git -f
git remote set-head origin -a
git fetch # fetch your commits from github
git reset origin/HEAD --hard # reset working tree to the remote

Git merge conflict with workspace.xml

I'm trying to push my Rails project to Heroku, but Git isn't allowing me to do anything at the moment. Here's what I've done so far:
git push heroku failed because the heroku branch was "ahead" of my local branch, which should not have been possible.
I pulled and there was a conflict with .idea/workspace.xml. I wasn't able to find out what that file is, but it's huge and Git wrote all kinds of garble to it. Too much to manually "resolve" conflicts.
I saw some stackoverflow posts talking about git-ignoring that file (maybe it's some IDE file for RubyMine or something?), so I tried to move the file away to avoid the conflict
I ran git add -A (also tried git add . and git add)
git commit --amend fails because "You are in the middle of a merge"
git merge --abort fails because "Untracked working tree file '.idea/workspace.xml' would be overwritten by merge (despite the fact that the file has been moved)
git reset --merge fails for the same reason.
How can I make Git work again?
.idea/workspace.xml
This file is your idea workspace files. They are generated by IntelliJ tools.
I saw some stackoverflow posts talking about git-ignoring that file (maybe it's some IDE file for RubyMine or something?), so I tried to move the file away to avoid the conflict
Simply add the folder to your .gitignore but since its already committed you will have to remove it from the repository:
# Quit the merge
git merge --abort
# remove the whole folder from the repo
git rm -rf --cached .idea/
# add it to the .gitignore: idea/
# add and commit your changes
git add .- A
git commit -m " Removed idea folder"
git push origin <branch>
If you still unable to do it?
First reset the code to the previous state and then do the above code again.
The reset will take you to your last commit before the pull
git commit -am "message" worked (as opposed to amending a commit)
I have resolved a similar problem by simply deleting the workspace.xml file. By building and running the program again idea will autogenerate a compatible file.

GIT confusion with restKit

So i am learning to ever so slowly use git to get me the latest update of RestKit as the old version has retain cycles...fair enough HOWEVER, when i pull using the gitHub Client it does not give me the AFNetworking files, which i was then told use the command
git submodule update --init --recursive
which i do, problem is that i noticed that after running that i run
git submodule status
It has taken me off the master branch and put the HEAD back in thus reverting me to old stuff. and hence back to leaks and stuff.
So i thought maybe i could install using cocoapods or perhaps put a submodule within the restkit submodule for AFNetworking...all did not seem to work and now i have followed this guide How do I remove a submodule? up until the last step as i dont know what committing will do? i hope it does not commit the fact that i deleted everything onto the restkit site? i am so confused, initially all i wanted to do was switch the current branch submodule i have to the master.
Assistance would be much appreciated.
EDIT:
Okay as to answer what Commit does, commit only affects your copy of the repository and will in no way affect the remote "main" repository everyone else gets their code from, so in essence i was able to commit it, then run a brand new submodule from the branch i wanted, But the question still remains Is there a way to switch the branch you pull your data from when using the update with --recursive?
Simply go in th e RestKit directory and type:
git pull origin master
(if you use the master branch of course)
Also, if you need to update all your submodules, just go to the root of your project, and type:
git submodule foreach git pull
git submodule update is confusing, here what it really does:
When you invoke git submodule update it looks in the parent repository for a SHA for each submodule, goes into those submodules, and checks out the corresponding SHAs.
As would be the case if you checked out a SHA in a regular repository, this puts the submodule into a detached HEAD state.
EDIT
To switch branch of a submodule simply, let say 'development', simply do in the submodule git checkout development and then you should be able to do git pull origin development

Setting up Github on a new computer

I am an almost perfect beginner at Github so please humor me with this elementary question.
I have a laptop PC that I've been using to interact with a repo on Github. I just bought a Mac and I would like to do my programming on both machines.
I have installed Git on the new machine and I have set up my username, e-mail, and Github token on the Terminal.
What are the basic commands I need to do this:
Download the repo from Github the first time? I've created a new folder on my Mac but going there and typing git pull git#github.com/sscirrus/repo.git produces fatal: not a repository (or any of the parent directories): .git.
Upload those changes again such that the main repo is updating cleanly with each new push. I assume that once I have the code in my new folder, it would be a matter of git add . and git push with password entry?
I am reading through tutorials on Git but just want to make sure I'm doing something sensible for my situation before my newbieness screws up a lot of prior work. Thank you!
Go through this book, http://progit.org/book/ and http://gitcasts.com/ for video tutorial.
And I recommend you follow these steps
Clone the repository (git clone repoAddress)
create a new branch (git branch branchName)
checkout that branch (git checkout branchName)
make changes and commit in that branch (git add files)
checkout master (git checkout master)
perform a pull (it updates the local repository with the remote one) git pull
If there is change, checkout the branch and rebase it with local master
If there is conflict resolve it and add that file and make a commit again
checkout master again and merge the branch (git merge branch)
push the commits to the remote repository.(git push)
If you want a GUI tool, then there is GitX which is made for Mac OS X. http://gitx.frim.nl/
Download the git repo for first time - do a clone of the repo first. this will bring your code from github to your machine for the first time.
git clone your_git_repo_url
from second time, you can
git pull your_git_repo_url
Upload the changes after commits
git push your_git_repo_url
Please read scott chacons git books. these will get you the basics of git. and learning this will help in the long run.
You need to use git clone, not git pull.
You'll want to git commit after add and before push. add just adds something to the index (Worst name ever. The "index" is essentially a pending commit.) and commit actually commits it to your repository. push then pushes committed stuff from your local repository to a remote repository.
Whilst there's a lot to be said for using git from the command line (to help understanding) you might like to try the github clients (for mac & windows - download them from the github homepage - at the bottom in the section marked 'clients') which I'm guessing might not have been available when you posted your question.
The Windows one lets you specify a default storage directory (where it clones the repos into) - the Mac one prompts you with each clone as to where you want to stick it.
Both very easy to use to do what you want (clone, pull, push etc and also good for seeing what branches you have and changing between them)
