Restaurant | restaurant application built with Javascript ES6 | Script Programming library

i wrote the node js get api with restaurant details. result is fine. how to get the map with required fields? bulk of fields are there but i required 2 fields only restaurant name and address. i am learning node js.

I am having a table that stores ratings of a restaurant. As shown in the below image.

I am trying to get the average of all these columns in which I am being successful but I also want an average of all these averages as a main average.

I tried the below query but I am getting 3 as average rating which is not accurate. I think mysql is returning me a round value of the final result.

Please help me. I have these 3 tables, and I have problems on how to call the category name based on the restaurant id from Controller to view. Thank you in advance.

Table items

Table categories

Table restorant

This is my Controller

I have a request that will return restaurant offers

console.log(offers) inside the for loop, returns what am I want (array with objects) but when I send the offers to the client with res.send(offers) return an empty array

what I should to do?

Hello I have this variable in php with data but in some pages I don't have it defined so I need to replace it with some data but my code doesn't work.

$item->restaurant->name

Try with:

$item->item_category->name = "Mi content replace";

But it does not work. What am I doing wrong? Thanks

Problem

I have a large JSON file (~700.000 lines, 1.2GB filesize) containing twitter data that I need to preprocess for data and network analysis. During the data collection an error happend: Instead of using " as a seperator ' was used. As this does not conform with the JSON standard, the file can not be processed by R or Python.

Information about the dataset: Every about 500 lines start with meta info + meta information for the users, etc. then there are the tweets in json (order of fields not stable) starting with a space, one tweet per line.

This is what I tried so far:

1. A simple data.replace('\'', '\"') is not possible, as the "text" fields contain tweets which may contain ' or " themselves.
2. Using regex, I was able to catch some of the instances, but it does not catch everything: re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
3. Using literal.eval(data) from the ast package also throws an error.

As the order of the fields and the legth for each field is not stable I am stuck on how to reformat that file in order to conform to JSON.

Normal sample line of the data (for this options one and two would work, but note that the tweets are also in non-english languages, which use " or ' in their tweets):

Is there any better way for doing this using plain javascript or using lodash package. I feel this code is a bit ugly and violates the DRY principle.

I have recently upgraded my flutter to the latest version and I am getting all the null safety errors.

Cant figure whats wrong with my axios call. Any help would be much appreciated.

So I have a search bar onClick that will send search terms to a function that compile the Api query string.
