Autoindex for multiple (specific directories)

[vsoch]

Hi,

I want to define a custom route for the root (@root("/")) and then auto index only a specific set of directories from there. However, when I define multiple autoindex, it tells me that I am overwriting existing end point functions. For example:

app = Flask(__name__)
timeseries_index = AutoIndex(app,"/var/www/timeseries",add_url_rules=False)
rna_index = AutoIndex(app,"/var/www/rna-seq",add_url_rules=False)
meta_index = AutoIndex(app,"/var/www/timeseries",add_url_rules=False)

# Custom indexing
@app.route('/timeseries')
@app.route('/timeseries/<path:path>')
def tindex(path='.'):
    return timeseries_index.render_autoindex(path)

# Custom indexing
@app.route('/rna-seq')
@app.route('/rna-seq/<path:path>')
def rindex(path='.'):
    return rna_index.render_autoindex(path)

# Custom indexing
@app.route('/metabolomics')
@app.route('/metabolomics/<path:path>')
def mindex(path='.'):
    return meta_index.render_autoindex(path)

# Main myconnectome analyses page
@app.route('/')
def show_analyses():
       ...etc

I get the same error when I move the *_index inside the route functions.

Error:

      Traceback (most recent call last):

    rna_index = AutoIndex(app,"/var/www/rna-seq",add_url_rules=False)

Is there a better way to do this? The above functionality works only given that I define the AutoIndex once (eg, for one subdirectory). However I need to do it for several. Thanks for your help!

This example is on python 2.7 not more supported

Hi @WolfgangFahl ,

Could you put more information : code, how to reproduce ...

Thanks

[apodobytko]

This is how you can reproduce:

bc@anton-mbp ~/H/p/v/autoindex_multiple [1]> tree
.
├── app.py
├── first
│   └── 1.txt
└── second
    └── 2.txt

2 directories, 3 files

bc@anton-mbp ~/H/p/v/autoindex_multiple> cat app.py
from flask import Flask
from flask_autoindex import AutoIndex

app = Flask(__name__)

first = AutoIndex(app, "first", add_url_rules=False)
second = AutoIndex(app, "second", add_url_rules=False)

@app.route("/first")
@app.route("/first/<path:path>")
def first_index(path="."):
    return first.render_autoindex(path, endpoint=".first_index")

@app.route("/second")
@app.route("/second/<path:path>")
def second_index(path="."):
    return second.render_autoindex(path, endpoint=".second_index")

if __name__ == "__main__":
    app.run(debug=True)

thx for stepping in

[general03]

It's FlaskSilk issue because you can't have several app on the same path.

[general03]

A rework is needed, detach this library

[flynn1973]

got same error today while trying to use multiple indexes in specific directoriers...any chance to get this fixed?
