I have this method in the ParametersController class:
public string SaveParameter(int id, string param, string val)
{
ProjectConfigurations config = new ProjectConfigurations();
ProjectConfigurationsDAO dao = new ProjectConfigurationsDAO();
config = dao.GetProjectConfigurationsByProjectAndParameter(id, param);
config.Value = val;
dao.Edit(config);
return JsonConvert.SerializeObject(new { success = true, data = config });
//return JsonConvert.SerializeObject(config);
}
In my BaseDao class, I have this:
public void Edit(T entity)
{
using (context = new Context())
{
context.Entry<T>(entity).State = EntityState.Modified;
context.SaveChanges();
}
}
The record is not updated. I'm new to EF, what I'm I doing wrong?
never try to create any generic repository since they are uselless. Try this
public string SaveParameter(int id, string param, string val)
{
using (context = new Context())
{
var existedConfig=conext.Set<Config>.FirstOrDefault(i=> i.Id==id);
existedConfig.Value=val;
context.Entry<Config>(existedConfig).State = EntityState.Modified;
context.SaveChanges();
return JsonConvert.SerializeObject(new { success = true, data = config });
}
