Mutation | Halo 2 content creation tool

I figured it out! Randomly placing voters in each district is not correct, and honestly it was pretty silly of me to do so. Instead, I had to use dplyr to create a data frame with the number of Democrat and Republican votes in each of the 435 House districts, one district per row. Then, I followed the advice on page 12 of this paper. I created samples of 18 districts sampled from this 435-row data frame, rejecting them if the mean vote share was more than 1 percent away from that of PA. The results have a much nicer 95% confidence interval, that matches the results of the original article.

TL;DR You are missing some resolvers. Your query resolvers are trying to do the job of the missing resolvers. Your resolvers must return data in the right shape.

In other words, your problems are with configuring Apollo Server's resolvers. Nothing Lambda-specific, as far as I can tell.

GraphQL doesn't know how to "resolve" an author's books, for instance. Add a Author {books(parent)} entry to Apollo Server's resolver map. The corresponding resolver function should return a list of book objects (i.e. [Books]), as your schema requires. Apollo's docs have a similar example you can adapt.

Here's a refactored author query, commented with the resolvers that will be called:

Laziness to the rescue. We can recursively define a list of all the sub-automata, such that their transitions index into that same list:

As you said, If you are getting error for mutation only, May be you are passing wrong token or wrong data.

Please check twice your code, must check token is passed whether it is valid or not.

Depends on how complex your application will get. One option is two-way data-binding as explained here: https://v3.vuejs.org/guide/component-basics.html#using-v-model-on-components

So you basically emit the changes to the parent.

For more complex applications I wouldn't pass data that are used in multiple components as props, but use a store. Either a simple reactive object; with provide/inject or use something like Vuex.

Vue 3+

lover versions probably has this method too but im not sure.

Because it's a named export you should return an object in the mock

This is one of the main challenges when working with SSR. So there's a process called Hydration that happens on the client after receiving the response with static HTML from the server. (you could read more on this Vue SSR guide)

Because of the way Nuxt is built and how the SSR/Client relationship works for hydration, what might happen is your server rendering an snapshot of your app, but the async data not being available before the client mounts the app, causing it to render a different store state, breaking the hydration.

The fact frameworks like Nuxt and Next (for React) implement their own components for Auth, and many others, is to deal with the manual conciliation process for correct hydration.

So going deeper on how to fix that without using Nuxt built-in auth module, there are a few things you could be aware of:

1. There the serverPrefetch method, that will be called on the Server-side which will wait until the promise is resolved before sending to the client to render it
2. Besides the component rendering, there's the context sent by the server to the client, which can be injected using the rendered hook, that's called when the app finishes the rendering, so the right moment to send your store state back to the client to reuse it during hydration process
3. On the store itself, if you're using registerModule, it supports an attribute preserveState, that's responsible for keeping the state injected by the server.

For the examples on how to work those parts, you could check the code on this page

Last, more related to your user auth challenge, another option would be to use nuxtServerInit on store actions to run this auth processing, since it'll be passed directly to the client afterwards, as described on Nuxt docs.

On the same page, the docs present that the first argument on the nextServerInit is the context, meaning you could get the store, for instance, from there.

Also one important point to mention, is that on your original question, you've mentioned that you don't want 3rd party libs, but you're already using one that brings a lot of complexity to the table, namely the nuxt-property-decorator. So not only you're dealing with SSR that's as complicated as it gets when using frameworks, but you're not using pure Vue, but Next, and not using pure TS Nuxt, but adding another complexity with decorators for the store.

Why am I mentioning it? Because taking a quick look on the lib issues, there are other people with the same issue of not accessing the this correctly.

Coming from a background of someone that used both Nuxt (Vue) and Next (React), my suggestion with you is to try to reduce the complexity, before trying out a lot of different stuff. So I'd test running your app without this nuxt-property-decorator to check if this works with the out-of-the-box store implementation, ensuring it's not a bug caused on the lib not fully prepared to support SSR complexity.

Since C++11, std::string::c_str() and std::string::data() are both required to return a pointer to the string's internal buffer. And since c_str() (but not data()) must be null-terminated, that effectively requires the internal buffer to always be null-terminated, though the null terminator is not counted by size()/length(), or returned by std::string iterators, etc.

Prior to C++11, the behavior of c_str() was technically implementation-specific, but most implementations I've ever seen worked this way, as it is the simplest and sanest way to implement it. C++11 just standardized the behavior that was already in wide use.

UPDATE

Since C++11, the buffer is always null-terminated, even for an empty string. However, that does not mean the buffer is required to be dynamically allocated when the string is empty. It could point to an SSO buffer, or even to a single static nul character. There is no guarantee that the pointer returned by c_str()/data() remains pointing at the same memory address as the content of the string changes.

std::string::substr() returns a new std::string with its own null-terminated buffer. The string being copied from is unaffected.
