mysql - The INSERT statement conflicted with the FOREIGN KEY constraint2 -


the insert statement conflicted foreign key constraint "fk_job_posting_client". conflict occurred in database "resland", table "dbo.client", column 'id'. statement has been terminated.

i got above exception message while inserting data in job posting screen database design job_posting table is:

  insert [dbo].[job_posting]        ([comp_id]        ,[res_id]        ,[res_type]        ,[contact_name]        ,[contact_info]        ,[title]        ,[descr]        ,[prerequisites]        ,[skills]        ,[job_type]        ,[location]        ,[duration]        ,[post_dt]        ,[post_end_dt]        ,[positions_cnt]        ,[client_id]        ,[category]        ,[rate]        ,[perks]        ,[stat]        ,[is_deleted]        ,[cr_by]        ,[dt_cr]        ,[mod_by]        ,[dt_mod])

in controller wrote code :

    [validateinput(false)]      //[validateantiforgerytoken]     [httppost]     public actionresult postjob(postjobmodel model, string btn)     {          if (btn == "save")         {              job_posting jobpost = new job_posting();              jobpost.res_id = rl_constants.res_id;             jobpost.res_type = rl_constants.res_type;             jobpost.comp_id = rl_constants.comp_id;             jobpost.post_dt = convert.todatetime(model.post_dt);             jobpost.post_end_dt = convert.todatetime(model.post_end_dt);             jobpost.positions_cnt = convert.toint32(model.positions_cnts);             jobpost.job_type =convert.tostring(model.job_type);             jobpost.duration = model.duration;             jobpost.category = convert.tostring(model.category_id);             jobpost.prerequisites = model.prerequisites;             jobpost.location = model.location;             jobpost.rate = model.rate;             //client=model.client_id             //client_id=(model.client_id)             jobpost.title = model.post_title;             jobpost.descr = regex.replace(model.description, @"<[^>]+>|&nbsp;", "");              jobpost.contact_name = model.contact_person;             jobpost.contact_info = model.contact_phone + "/" + model.contact_email;             jobpost.skills = model.skills;             jobpost.perks = model.perks;             jobpost.dt_cr = datetime.now;             jobpost.cr_by = rl_constants.user_name;             jobpost.stat = "active";             jobpost.is_deleted = "n";              reslandentity.job_posting.add(jobpost);             reslandentity.savechanges();         }         return redirecttoaction("jobsearchlist", "employer");     }

where problem

the error message says client id you're using doesn't exist in client table. setting cliendid fk reference correctly? in code you've posted setting of clientid has been commented out. means clientid = 0 (if it's int), , bet don't have clients id = 0.

---- update ----- clientid = 0 tries make fk relationship client table, fails. said didn't want use clientid @ point , clientid column nullable. i'm not sure why it's assigned 0 value, check it's working should clientid = null in mapping. should prevent ef trying make fk relationship.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
