Subject: [Flask] [flask-sqlalchemy] lazy = True Option
Message-ID: <MAXPR01MB2653477B8602B1F118227E82B47A0@MAXPR01MB2653.INDPRD01.PROD.OUTLOOK.COM>

Hi all

I am using Flask / flask-sqlalchemy  and postgres DB for web application and currently facing issues w.r.t performance i.e. high cpu / memory  / response time.

We have many tables with one to many relationships  . I have below queries :-


  1.  In terms of performance what is the difference between lazy = True or lazy = dynamic  option.
  2.  As of now at table mapping level ,  loader options are defined . Is  there any reference on how to define at query level . Will  it help to improve the performance  ?
  3.  If we have many level of nesting (parent  - child relationships )  , is it possible to exclude certain relationships selectively ?
  4.  For search  feature , can we setup  index parameter for frequently used columns. If yes , any reference ?

Regards
Nitin

Subject: [Flask] intermittent Internal Server Error on running flask site
Message-ID: <JCWFwrEztINIt6AznVX6K2JHaCDx59vLqzsxC5sUaZUl3QZ7yunoR-TbDLVx1S271-LPMwJEsMtuiNytyIwhcyaBBc4rewvbc3NOaz_v6vM=@protonmail.com>

Hello all:

I'm just looking for pointers on where to check, in order to track this down.

The problem:

I have a production flask site,
on Apache /2.4.38; Debian 10.1, using a virtualized Python3.5/HTML5 site.

It works well! except that every few days it crashes with an Internal Server Error - 500.

When "crashed", the site itself is still loaded in Apache2,
as
nmap -A <my ip>
nmap -sP <my ip>
nmap -A <mydomain>
nmap -sP <mydomain>
all report the host is loaded;
and other static sites running on the same apache server still serve up just fine.

It does not *appear* to be a coding error,
as when it is running,
I have negotiated to each and every page in the site,
without causing a crash.

Still, randomly, the site fails.

I have been through:
* the web sites' error.log
* the web sites' acess.log
* /var/log/apache2/error.log
* /var/log/apache2/error.log.1
* /var/log/syslog
and I'm not finding the cause.

A
sudo systemctl stop apache2.service
sudo systemctl start apache2.service
gets the site running again.

Any tips on where else to check?

Thank you!

The Error
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Is there a list of other flask-related interactive(ish) resources
to help with questions?

Other mailing lists? etc?

I know there is a flask chat out there, but searches aren't finding it for me.

Thank you

Are you familiar with LaTeX? If so, you could use use normal Jinja2 
templates for .tex files, and generate pdfs from those resulting files.

Are you planning to generate these reports live (ie. when users load 
the page on your site) or only locally (eg. having a local Python 
script that analyses your Flask and outputs the report to a PDF file)?

Hello,
I wonder. If you know rougly when it happens perhaps there's some info
in the access log to indicate what the request was at that time? It
could be that there's some request coming in that perhaps your code is
not able to handle and causes the 500 error?

Okay. Since I haven't used LaTeX much I don't have a clear idea of how 
long it'll take, but for most cases (say, plaintext + a few images) the 
compilation won't take more than a second or so. So if you can make a 
template for a LaTeX file (using the Flask/Jinja2 templating system), 
you could do something like:
Create a temporary folder (maybe using `tempfile.mkdtemp`)Write the 
LaTeX file to that (the result of render_template)Run pdflatex on that 
LaTeX file, maybe using `os.system` or a more fine-tuned commandOutput 
will be the same name with the .pdf extension: for example abc.tex will 
render to abc.pdfServe that abc.pdf file to the user.
Hope that helps. Let me know if you need more info on the tempfile 
library, since I've been working with it in one of my projects.

That's just it --- I am not seeing the errors on the logs.

Am I missing a place to check?

I haven't worked with printers, but this should also be possible by 
appending a command in the appropriate library to whatever script 
you're using.

(To clarify, in the steps I listed above were meant to be automated, 
not done manually by the user).

Let me know if you want more details. Not sure how much help I can be, 
but I'll do my best :)

Message-ID: <84E1AEDC-2451-4938-B155-1A11906A9309@akamai.com>

Hi,
This is not a Flask question, but more of a python question. I have root logger configured and a rotating file handler added to the root logger. I am using some format string to display the log lines. However, once the log rotation is done, the format string is not used at all in the new log file. The log lines are printed as is without any format string.
Has anyone encountered a similar issue ?

Thanks,
Prakash

Message-ID: <CAC10dPbfUWzeOfFiXoo1EAPbH=DhfR5XG4mAmtSeMdyzB1SxDQ@mail.gmail.com>

I'm implementing  CRUD under blueprints.
I've a admin.py which contains the following routes:

@admin.route('/groups', methods=['GET', 'POST'])
def groups() :
# Do some stuff

    form = Group_pick()
    groups = groups_table.query.order_by(groups_table.gp_office).all()
....
@admin.route('/groupmaint/<gpid>', methods=['GET', 'POST'])
def groupmaint(gpid) :
# Do some stuff
 ..........

And the html in the groups has the following:
......
<tbody style="height:150px;">
     {% for group in groups %}
      <tr>
       <td style="width:150px;"> {{ group.gp_groupid }} </td>
       <td style="width:389px;"> {{ group.gp_name }} </td>
       <td style="width:150px;"> {{ group.gp_type }} </td>
        <td style="width:75px;">
         <button>
            <a href="{{ url_for('admin.groupmaint', gpid=group.gp_groupid )
}}">
            Edit
         </a>
         </button>

.....
When the edit is clicked, it DOES get to the :
@admin.route('/groupmaint/<gpid>', methods=['GET', 'POST'])

However, all the css, js and other imported goodness is missing and not
found.

What do I need to do to correct this?

*Thanks ...*

Hi all,

The foremost thing to remember is that in flask, sessions are tied only to
request context. Simply put, the session is available only during the
lifetime of a request.

Yes, session can only be accessed within a request context, which would 
in practical terms mean it needs to be called from within a view. Each 
client (read: browser) which loads the page gets its own session, so it 
doesn't make sense to define a "global" session for everyone.

Depending on what you're trying to do, you could set the session 
variable within a view like

@app.route('/')
def home():
     session['myvar'] = 'MYVAR' # sets variable for this particular session
     return 'Hello, session!'

On the other hand, if you want the variable to be global for the whole 
app, you should probably be setting app.config or something instead of 
using session variables.

Hope that helps!

Badri
