Trying out a program that tries to systematically scrape from a store locator page that requires address input. I'm trying an approach that involves making requests over a grid of latitude/longitude coordinates, and using Google to automatically convert it to an address. The problem is that some of the coordinates of the grid will be in the ocean and not have addresses, so that scenario will probably require a long workaround.

For now, I'm skipping those coordinates and hoping that won't cause the scan to come up short. The workaround is probably going to involve automatically finding the nearest ZIP code from this spreadsheet which has a coordinate associated with each

Edit: I found the workaround. It involves splitting the grid unit centered in the ocean over and over until reaching a grid unit of a specified width, keeping the subunits that are on land, and discarding the ocean grid units once they've been split too much so the width is below the minimum

today I managed to work around my block on implementing this feature that I was "sure" I could fit into the data structure I designed by using a combination of exploiting the use of display/editor templates in .net mvc to create a display template that is actually used to passively edit an object that is populated using html returned from an editor in a modal that is bounced via a controller and appended to the original display list.

there's also reflection and accessing of fields to get paths to templates to render default html and oh god what have I done am I now the monster???

The worst thing about web scraping is having to wait as long as 20 hours to see if a program collected all the records so that the number of records matches up with what it should be. I'm waiting for it to finish so I can see if my fix for the "no address exists for a latitude-longitude coordinate in the ocean" problem works

I guess I could have told the program to collect all the locations in a boxed area bounding the borders of Maine instead of the entire U.S., but it's been long enough I might as well finish it now

idk if this is terrible or genius....the data structure in the db is a completely flat, single table that represents multiple types of thing, those things can parent one another to create a (theoretically) infinitely deep tree that is renders to the UI by iterating through each one. a "thing" can be any one of a list of predefined elements like a dropdown list, text field etc, so effectively you've got a dynamic form that will save into a common data model.

ive then added the ability for a "thing" to parent a list of things that can be dynamically added to, on page, such that when you submit the entire page back, all your things get iterated over and saved into the model without the MVC binder blowing up. i think.

this has involved about 3 solid days of staring at the screen to get this far and i dont know if im now the idiot or what

# ? Oct 23, 2018 23:23

Powerful Two-Hander: Mar 10, 2004; Mods please change my name to "Tooter Skeleton" TIA.

like, generally the mvc razor views and model binder are really loving good, but once you get into nested items in your models it either works "as is" or.....you end up handcrafting a load of poo poo to create the element structure your model needs so that when you post back it all binds properly and provides the properties you need to do whatever it is you need with it.

it all makes sense but god drat does it make for some complicated view code.

i hope you are rate limiting

# ? Oct 23, 2018 23:48

galenanorth: May 19, 2016

Yes, I am rate limiting at about one second per request. Nearly all the requests are to Google and they have a 40,000 free requests/month cap so I'm hoping the scan completes before reaching that amount. I realized that I should start saving every Google response in a file, so when I repeat the scan to check whether anything has changed, I won't have to send the requests again. That'll allow the scan to progress 100x faster after the initial scan.

it's terrible in python as well, maybe worse since python code tends to be less overload-crazy in general

your non-async version is technically 'better' here because it can run all the someAsyncFunction calls in parallel, which may or may not matter more than code clarity
i would expect something maybe like
code:
var promises = items.map(item => someAsyncFunction(item)
    .then(result => ({a: result, b: item.someProperty})));
return Promise.all(promises);

yeah that bit wasn't actually me, that's been around for like 10 years, I just added stuff to it. like the rest of this, it's either really good or really bad depending on how you look at it.

there are other tables involved to define the structure but there is one big table that stores the actual data. like if you have a record in tblThings called "butt" it could have child records in tblThings called "fart1, fart2 etc", but the actual values of all your butts and farts would be flattened out into tblvalues.

like I said, it's either really good or really bad depending on how you look at it

# ? Oct 24, 2018 09:29

Powerful Two-Hander: Mar 10, 2004; Mods please change my name to "Tooter Skeleton" TIA.

Well, it's more like a key value table. the related 'normal' tables produce a concrete hierarchical model that then has its values "filled" from the shared value table that just stores a reference to the model element and its value

the view then just iterates over the elements in the model rendering a pre defined html chunk for each. so it's a templating engine basically, by defining the structure you want in the DB the ui will render a form that captures all of the data and saves it back into a single dataset.

this has been running for like 10 years, originally with some horrid database to xml to javascript to html and back conversion layer, now thats all done in the mvc framework with templates... these have just got a bit complicated when you start dynamically adding elements to the page because you have to make sure that they conform to what the model binder expects and debugging binding issues loving suuuckkks.

also keeping it all generic requires all sorts of tricks to extract properties from anonymous objects using reflection because although I know that a particular IButt implementation has an additional property of "ButtTitle", as its not part of the interface it isn't accessible directly.

oh yeah did I mention the data is also extracted out into a nested xml structure and distributed as well??

i should probably try and get permission to do a proper write up online or something

ha, not far off but no xml stored in the DB thank god. if I hadn't inherited this thing I'd have done it different for sure, but compared to the models used by consumers of the data where they have either ridiculously wide tables with column names like fart1 fart2 , fart3 etc. (and yes, this has caused their systems to blow up when fart4 turns up because our model supports lists of any length) or piles and piles of tiny tables that are hard bound to a specific thing.

you can create some absolutely heinous locking issues or mega queries though

probably yeah.

i mean, I've learned a hell of a lot from this thing, hence why if I was doing it from scratch I would do it differently.

Edit : this has just reminded me that we deal with a vendor who provide the same sort of data and their "schema" consists of a 1200 column wide flat file because they don't understand the concept of one to many relationships so have just created columns for as many child things as they think they might ever need.

oh and some of those columns contain comma separated data as well. I'll take our key value table over that any day, at least we can go back and forth between flat and nested structures easily.
