ParkCode

Edit//

I suppose my question isn’t so clear. I’m trying to get one park returned when my url points to http://localhost:1233/details/‘${parkcode}’. I’ve defined the param for the url in my results.js file. But I’m having trouble in defining the this.setState in my details.js to render just one result of the park based on the id which also happens to be the park code.

I'm new to React (and possibly to JavaScript, I don't know anymore). I am following a tutorial - instead of using an npm package for an API I decided to branch out and use axios.get() to fetch data from an API. I am able to render the results from a component into the browser, however after adding on reach-router (I assume it's similar to React Router), I am having troubles rendering just one result of my API call as the page I am attempting to build is supposed to only show ONE result based on the ID I have defined.

In my main file, which is Results.js here, I am able to get the data with no problem and include them in my file using JSX and render them. I'm attempting to use the same logic as I did in that page in my Details.js page (which is the page that is supposed to show only one result to the ID in the route).

How I'm using axios in Results.js

According to this question you can only send data from input forms from html to Python with POST. I'm trying to figure out how to pass a value (that's actually originally contained in a dictionary that I passed in from Python) from html to Python.

My two approaches I considered (and have not figured out how to do successfully) are:

1. Taking a look at the Flask quickstart, this should be quite simple. I'm just not sure what the syntax should look like on the html side to pass in this parkCode.

I'm trying to embed a call to a javascript function in a leaflet popup.

I'm binding the showPopup() function to each feature added to a map. The idea is when the user clicks on the feature, there is an href labeled "More info..." which should open a sidebar.

I'm attempting to pass in the features Code to the embedded 'javascript:getInfoPanelData(feature code here, say PIPE as example) to know which feature I'm working with. However, running this code in Chrome debugger yields

Uncaught ReferenceError: PIPE is not defined at :1:18.

I've also tried to add single quotes around the parameter, but this yields a SyntaxError:

Unexpected end of input (getInfoPanelData("red x" in debugger.

I'm not sure I can actually do what I need to do and am hoping someone can either point out my mistake or possible alternatives.

I have a widget which I want to update every time I update my database and want to show the content from the database on the widget even when the app is not running. My db is implemented using Room, and the widget is updated using an IntentService. Everytime an update is made, onHandleIntent will try to get the new entry from the db and update the widget.

But for the code below, it always returns a null List from the db

Is there an alternate way to implement this? AsyncTask wont work here as it requires execution on main thread.

I am new to Room and RxJava, so not sure if I missed anything obvious.

I know that the question has been asked before but none of the answers have answered it. I'm very confused so would really appreciate some help.

I have a JSON file:

I'm attempting to get park information from the National Park Service's API but res.on('data') is never getting called and I'm getting an error code of 503. This API doesn't have very much documentation and I don't have very much experience working with APIs so I could be missing something small and obvious.

I have been trying to make a GET request to the National Park Service API with axios and have tried several ways to set my API key in the request header to no avail. Any assistance will be greatly appreciated.
