Redmine

Hi Alice,
I think you would have to do a plugin.
It seems the date is set by retrieve_query in source:trunk/app/controllers/gantts_controller.rb
I don't have my IDE available right now so I'm not able to tell where is the definition of retrieve_query.
I guess you would have to wrap retrieve_query such as, if the date is not specified, you use the project's start date.
Make plugins rather than editing Redmine's code otherwise you won't be able to update to newer releases. Actually plugins can also break with updates but it's still far better.
Cheer,

I found the definition of retrieve_query, but I don't know if it's the method for the start date...

# Retrieve query from session or build a new query
def retrieve_query
if !params[:query_id].blank?
cond = "project_id IS NULL"
cond << " OR project_id = #{@project.id}" if Herve Harster
@query = IssueQuery.where(cond).find(params[:query_id])
raise ::Unauthorized unless @query.visible?
@query.project = Herve Harster
session[:query] = {:id => @query.id, :project_id => @query.project_id}
sort_clear
elsif api_request? || params[:set_filter] || session[:query].nil? || session[:query][:project_id] != (Herve Harster ? @project.id : nil) # Give it a name, required to be valid
@query = IssueQuery.new(:name => "_")
@query.project = Herve Harster
@query.build_from_params(params)
session[:query] = {:project_id => @query.project_id, :filters => @query.filters, :group_by => @query.group_by, :column_names => @query.column_names}
else # retrieve from session
@query = nil
@query = IssueQuery.find_by_id(session[:query][:id]) if session[:query][:id]
@query ||= IssueQuery.new(:name => "_", :filters => session[:query][:filters], :group_by => session[:query][:group_by], :column_names => session[:query][:column_names])
@query.project = Herve Harster
end
end

I have found the method for this (it's in lib\redmine\helpers\gantt.rb) :

@month_from ||= Project.start_date.month
@year_from ||= Date.today.year

But with this, I have this error :

NoMethodError (undefined method `start_date' for #<Class:0x2b6b0a8>):
lib/redmine/helpers/gantt.rb:59:in `initialize'
app/controllers/gantts_controller.rb:34:in `new'
app/controllers/gantts_controller.rb:34:in `show'

Can you help me please ?

Is there a way I can see your entire code? Maybe you have it on Github?
Cheers,

Hi,

Finally, I didn't wrote the plugin.
I just tried to change @month_from ||= Date.today.month (in lib/redmine/helpers/gantt.rb) by project.start_date but it didn't work.
So, I give up..

Looking for a similar thing.
In Gantt-Diagramm I'd like to see minimum one month in the past to review open issues.
Anyone able to give a hint?

I would like to change the Gantt to start from Project.start_date too, I have to workaround by starting from previous month for now
