asp.net web api2 - Web API 2 cannot register user -

-

i have web api 2 project using mvc. uses entity framework. entity framework uses database first approach .edmx file.

the project based on vs 2013 express web api 2 template. used own database. didn't modify account related code. when try register new user, following statement in accountcontroller.cs throw exception:

public async task<ihttpactionresult> register(registerbindingmodel model) {     ...     identityresult result = await usermanager.createasync(user, model.password);     ... }

the exception says:

cannot insert value null column 'discriminator', table 'xxx.dbo.aspnetusers'; column not allow nulls. insert fails. statement has been terminated.

can me? thank you!

the answer in question's body.

table 'xxx.dbo.aspnetusers'; column not allow nulls.

seems be, you're trying insert null value model instance registerbindingmodel model, structure of table in database server doesn't allow accept null value.

try debug , check, model instance creating correctly when request coming.

also can see, use:

identityresult result = await usermanager.createasync(user, model.password);

why user isn't member of model, password property? maybe try use:

identityresult result = await usermanager.createasync(model.user, model.password);

anyway... don't have more info , don't imagine, inside model instance, how you're binding data in request. should in debugger , debug repair project or provide more info.

but 1 thing clear crystal, you're trying insert null value column, doesn't accept null, must check how model binding. maybe client-side application doesn't send correctly arguments, maybe you're binding model incorrectly, maybe else... there need more information you, otherwise should debug carefully.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
