How to get commit history of users in gitlab in rails - ruby

Question

I am trying to create an app which will fetch the gitlab/github commit history of the user which i can just show in a side panel and it can be checked on or off depending on my criteria. I want to know if there is a way to fetch the current logged user's gitlab/github commit history. I tried to use the gem
https://github.com/libgit2/rugged
But couldn't find a way to implement my need. If anyone knows how to implement this it would be so much helpful. Thanks.
Update
I have now managed to get the user by using :
Gitlab.endpoint = 'https://gitlab.com/api/v4'
Gitlab.private_token = 'token'
g = Gitlab.client(
endpoint: 'https://gitlab.com/api/v4',
private_token: 'token',
httparty: {
headers: { 'Cookie' => 'gitlab_canary=true' }
}
)
By using the command g.user i am able to get the user but i need to get the commits of the user that he has done in gitlab.

Use this gitlab API GET /projects/:id/repository/commits to fetch all the commits on a repository gitlab api. Check the attached code for more details.
Basically this git log --author="user_name" command can give you git commit history for a specific user, you can even use email address just the first name or last name in the above command.
Once you have authenticated with gitlab you can run the following command from ruby.
cmd = 'git log --author="user_name"'
system(cmd)
Sample code form ruby to connect to gitlab using private token which is not ideal but just an example
require 'json'
require 'curb'
require 'net/http'
begin
def parseCoverageReport(report_text)
coverage_perc = report_text.match /All files\s+\|\s+(\d+\.?\d+).*\n/
if not coverage_perc then
coverage_perc = report_text.match /^TOTAL\s+\d+\s+\d+\s+(\d+)%$/
end
if coverage_perc then
#if we found coverage value in job trace
#puts "coverage_perc[1]: #{coverage_perc[1]}"
coverage_perc[1].to_i
end
end

end
end
send_event('open_merge_requests_table', table)

end
In the above ruby example please have a look at the following code snippet
merge_reqs = JSON.parse(Curl.get("#{gitlab_url}/api/v4/projects/#{project['id']}/merge_requests?state=opened&private_token=#{gitlab_token}&per_page=200").body_str)
git_project = JSON.parse(Curl.get("#{gitlab_url}/api/v4/projects/#{project['id']}?private_token=#{gitlab_token}").body_str)
opened_mrs = merge_reqs.select { |merge_reqs| %w[opened].include? merge_reqs['state'] }
repo_name = git_project['name']
repo_url = git_project['web_url']
In here what i am trying to do is connect to our gitlab instance using a private_token and then for a specific project id (which you can get it form the UI of gitlab) check for the open merge request. I also get the git_project from which i get the name and web_url (which was my use case).
For your use case you will have to get the project_id(for gitlab UI) and then use some appropriate method to get the commits.gitlab docs
