What controllers do you have?

M

Mayor McCheese•1/24/24, 5:07 AM

404 in this case means no index page was found

M

MastaOP•1/24/24, 5:13 AM

this is my view

M

MastaOP•1/24/24, 5:17 AM

i don't know if it helps but in the console inside of localhost:7072 is also empty with any errors when i check it

G

Gramore•1/24/24, 6:05 AM

Do you still have a Home controller for that

Home/Error

Home/Error

redirect in your Program.cs?

T

TeBeCo•1/24/24, 6:17 AM

T

TeBeCo•1/24/24, 6:17 AM

unrelated but this will need to be addressed later

GGramore Do you still have a Home controller for that `Home/Error` redirect in your Progr...

M

MastaOP•1/24/24, 9:27 AM

I dont have it anymore

MastaOP•1/24/24, 9:27 AM

This is a database that im using from MSql

G

Gramore•1/24/24, 9:33 AM

Mby add it back and see if that fixes your 404

MMasta This is a database that im using from MSql

T

TeBeCo•1/24/24, 9:34 AM

yes but calling

new

new

on the DbContext is a huge anti pattern in an MVC project

T

TeBeCo•1/24/24, 9:35 AM

you're supposed to inject the type directly in the ctor of the controller and never call

new

new

T

TeBeCo•1/24/24, 9:35 AM

this isn't related to your error

T

TeBeCo•1/24/24, 9:35 AM

it's a huge code smell though

G

Gramore•1/24/24, 9:35 AM

ye learning to love DI is a whole step in the learning process

TTeBeCo it's a huge code smell though

M

MastaOP•1/24/24, 9:41 AM

Ill try look into it better i was just trying to solve the issue with the startup of the project cuz it doesnt even load

M

MastaOP•1/24/24, 9:46 AM

Update i have add a HomeController to see if it would at least receive something and it appears the same i also tried changing the "Home/Error" to " Student/Error" and it loads and appears the same error

Cannot find this localhost pageNo web page found for the web address: https://localhost:7072/
HTTP ERROR 404

GGramore Mby add it back and see if that fixes your 404 🙂

M

MastaOP•1/24/24, 9:51 AM

it didnt work

G

Gramore•1/24/24, 9:58 AM

Then nothing obvious sticks out, next step might be to set the log level to info / verbose (with MS logs allowed to emit at that level) and see what it says

G

Gramore•1/24/24, 10:00 AM

should be a setting in your

appsettings.Development.json

appsettings.Development.json

for it

MMasta Update i have add a HomeController to see if it would at least receive something...

T

TeBeCo•1/24/24, 10:08 AM

did you tried

/student/index

/student/index

?

TTeBeCo did you tried `/student/index` ?

M

MastaOP•1/24/24, 10:10 AM

yes i did, still the same

T

TeBeCo•1/24/24, 10:18 AM

ok soooo

T

TeBeCo•1/24/24, 10:18 AM

you probably forgot to rename the fiel and the folder

T

TeBeCo•1/24/24, 10:19 AM

can you:

in VS
open the controller code
open the Solution explorer on the side
expand the Controllers folder
expand the Views folder

T

TeBeCo•1/24/24, 10:20 AM

my bet is that you "renamed code" but forgot to rename

HomeController.cs

HomeController.cs

file to

StudentController.cs

StudentController.cs

and also

Views/Home

Views/Home

folder has probably not been renamed to

Views/Student

Views/Student

T

TeBeCo•1/24/24, 10:20 AM

I just reproduced locally and renaming was the missing part

M

MastaOP•1/24/24, 10:20 AM

T

TeBeCo•1/24/24, 10:21 AM

are you using hot reload ?

M

MastaOP•1/24/24, 10:22 AM

im not im compiling normally

M

MastaOP•1/24/24, 10:23 AM

im suspecting of something

T

TeBeCo•1/24/24, 10:23 AM

T

TeBeCo•1/24/24, 10:23 AM

works for me

T

TeBeCo•1/24/24, 10:23 AM

M

MastaOP•1/24/24, 10:24 AM

look at this, isnt it supose to even send any message with an error ?

TTeBeCo Click to see attachment

M

MastaOP•1/24/24, 10:24 AM

it also worked for me perfectly a few days ago that's what im stressing about

T

TeBeCo•1/24/24, 10:24 AM

it's a 404

T

TeBeCo•1/24/24, 10:25 AM

there's no reason for anything in the console

T

TeBeCo•1/24/24, 10:25 AM

look at the C# logs

T

TeBeCo•1/24/24, 10:25 AM

T

TeBeCo•1/24/24, 10:25 AM

stuff like this

T

TeBeCo•1/24/24, 10:25 AM

T

TeBeCo•1/24/24, 10:25 AM

change that to be

Information

Information

in your

T

TeBeCo•1/24/24, 10:25 AM

and read the logs

M

MastaOP•1/24/24, 10:25 AM

M

MastaOP•1/24/24, 10:26 AM

this?

T

TeBeCo•1/24/24, 10:26 AM

yes
