at and many other places, suggestion. Vary the names a bit: form=form is ambiguous to me. Same with /about and about() .. if different a bit, then one would know what's referring to what.

How did you select two lines at the same time??
Thank God I know how to select ocurrences!!!
Can someone tell me how to do it in VsCode????
another good video - btw following along, I relaized at around that you do need to pip install email_validator - I may have missed that instruction in the earlier part of the video
im at in the video and i started ran my program flaskblogand this error showed up:
At I cannot load the Register page properly - I keep getting "builtins.KeyError KeyError: 'A secret key is required to use CSRF." on the page. I tried generating a new Secret Key and updating the app.config line in flaskblog.py with the new Secret Key (and saved) but the page still cannot load properly and shows the same KeyError page...
@ iam having trouble after completing the register.html template iam getting an error of jinja2.exceptions.TemplateSyntaxError: expected token ',', got 'form' is anybody having a problem, Please help
Hi I'm using spyder and I'm getting this error: cannot import 'url_encode' from 'werkzeug'
Quick question - Around on the Register page, you Labels are above the input fields, whereas mine are inline with the input fields which makes the page look weird. Any idea why this is happening? I compared our register.html and I believe they are identical...Any help would be great!
@Corey Schafer / 48:16 thank you so much Corey you are a gentleman and a scholar. I created the problem by placing a "/" in the action=" " area of the register.html I should of left it empty then in my research i found out that I can also use the url_for() function as well. my comments was more to help others that may have done the same mistake as I did. thank you so much I am now watching Part-4 and OMG it's a lot to take in as you said in the video "you have another section on OOP w/python" I definitely have to go thru that ... not sure if I should stop this series and go to the OOP series or finish this one.what do you recomend...
can someone help me with ,i m using python 2.7 what should that line be for python 2.7 interpreter
At the time , why did we use (dot)data in flash(f'Account created for {form.username.data}!'). ?Could follow till form.username
@Corey Thank you again for wonderful tutorial. Quick question @"if form.validate_on_submit():", how can we validate the form before rendering the template? Appreciate your response. Thanks
what is the alternative for *flash(f'Account created for {form.username.data}!', 'success')* I use python 3.5
At around , how is the render_template() function called before validate_on_submit() and anything else even though it is the last line in the function register()? With the fact that there is a return statement in the if function(return redirect())?
how can a method have two returns ? please explain
So I have completed everything up to and when I try to enter info on registration page I can't even click inside the box. So I am unable to enter any information. Any help?
about Flash
-- I'm stuck at of the video because it does not redirect to the home page.... any help would be appreciate
followed exactly everything word by word yet am not getting the success flash msg
Was entering invalid info at and thought I had a problem, many hours of googling late I realize my mistake by accident xDIf you got an error, just keep watching it might be solved right after!
i don't understand in if he has set that alert message in layout.html then when he refresh the register page , why didn't he get a flash message @coreymschafer i'm getting this flash message on every page except home page, lol............
were given at but once copying your code from github it works fine. Must be that I added another parameter to the template for site
I am not able to validate after I submit details on the register page. No action happens. Time: , plwease help
around the mark. Did anyone else have a problem with displaying the flask blog from this point onwards? Tried to compare my code with Corey's codebase yet to no avail!
My issue: I am up to the Register Form HTML, around . I see in red text is 'invalid field name "Password" ' below the input field for 'Confirm Password' EVEN THOUGH the fake information I entered are accurate. How do I disable the faulty notification?
I am getting a weird error around . I copied the code completely. I am not using bootstrap but when i put an invalid entry on the form, the error messages appear but the input class dissapears.
This confusing to me !How we can check if username wrong and we don't have username field yet?
If you're using PyCharm, Select all occurrences like:1) *Set multiple cursors* in the editor area: *Alt + Mouse Click* (Option + Mouse Click for Mac OS X). ...
"please fill out this field" but I want the same show in the video please let me know how to do thisthank you so much
years later, like me,,,, at , 'This field is required' doesn't show up on my chrome or firefox browsers when the fields are empty. Red outlines still show. I spent a lot of time scratching my head on this. Then eventually went to Corey's GitHub and tried his code... same thing, so maybe something has changed? However, I think I'm still missing something because when I replace {{ error }} with a string like "this is an error" in the html it still doesn't show.
Which Bootstrap classes? Can anyone please tell. I'm not getting this type of error. Getting {{ error}} instead.Thanks.✌️🙂
@Corey Schafer at about when checking the form error messages, yours shows text under the text fields "This field is required," mine only shows the text fields outlined in red. Any idea why this would be different? I believe my code matches yours to the letter.
at , when I press submit while leave all the fields in this form blank, I got a small yellow ! icon with text "Please fill out this form" at the username field rather than all error message at four fields like what Corey did. Is this because of the Flask module update or I did something wrong? I also use Corey's code from repository and I got the same behavior.
Anyone else missing the 'This field is required' text at ? Even after copying the register.html from his github I'm still not getting that.
For the form validation at , when he doesnt input anything, it says "This field is required". For me, it shows a message popup for username, saying "Please enter this field". I copied all his code, is this just an update thing?
Around ,1. I found that your form validation shows all fields are required when empty form is submitted; however, when I tru the same, only username field is shown by the validator.2. In username, when you enter single character and submit the form, it gives you min and max length; however, it does not show any such validation in my output.
/ 48:16 Sorry validators are not taking effect, not even the Length()min=2, max=20 on username nor do I get the red outline on the boxes, any thoughts
Is there something wrong with this video or with my pc? I see blurred and distorted screen sometimes- at , 44:43, etc.
@ You don't need validation on the checkbox. ..... Erwin Schrödinger: Challenge accepted! Hold my beer... :D
I'm sure it's just a bug in my code. But I ran into a problem at with my "Login" button. It was a "Sign Up" button instead. On line 40 of "login.html" I used this code instead:
I am getting 'method not found error' in the page. I don't understand what went wrong.
I believe the flash message should be "Please check email and password" ... not "user"
Around when he is talking about using the multi-select functionality he never tells you how to do this. For those that didn't know it existed you select the first instance of the word you want to replace (double click the word to select it quickly) then use the key combination CTRL-D which will select the closest next instance of the same word you have selected. Keep hitting CTRL-D until you have all the ones you want to replace selected. Then you can just type in your change and all selected words will get what you type in.
